Men’s Swimwear Briefs at the Beach: Why Men Are Switching From Shorts to Briefs, Bikinis, and Thongs

For years, men's beach fashion seemed almost ridiculously predictable.

Women had dozens of choices: one-pieces, bikinis, Brazilian bottoms, cheeky cuts, thongs, strings, micros, and countless variations in between.

Men?

Put on a pair of shorts.

Often they weren't even particularly short. Board shorts became so dominant that men's swimsuits sometimes extended almost to the knees.

But men's swimwear is changing.

The modern beach increasingly offers men a much broader spectrum of choices, from shorter trunks and square cuts to classic swim briefs, bikinis, Brazilian cuts, thongs, G-strings, and micro swimsuits.

And for a growing number of men, once they discover how comfortable a small swimsuit can be, going back to oversized shorts isn't particularly appealing.

The Return of the Men's Swimwear Brief

The swim brief never actually disappeared.

Competitive swimmers continued wearing streamlined briefs because they are practical in the water. Brief swimwear also remained familiar in many international beach cultures even during periods when long board shorts dominated American men's fashion.

What has changed is the attitude surrounding them.

A man doesn't have to be a competitive swimmer to wear a swim brief.

He doesn't need a certain body type.

He doesn't have to be gay, straight, or bisexual.

He doesn't have to explain why he isn't wearing shorts.

A swim brief is simply another swimsuit.

That sounds obvious, but culturally it represents a fairly important change.

Why Did Men's Swimsuits Become So Big?

Fashion goes through cycles.

During the rise of surfing and board-short culture, loose and increasingly long shorts became fashionable for men. Eventually, even guys who weren't going anywhere near a surfboard were wearing board shorts at swimming pools and beaches.

For some men, that style remains ideal.

But other guys eventually started asking a very simple question:

Why am I swimming in shorts?

If you're sunbathing, swimming, relaxing at a resort, or walking along a beach, you don't necessarily need all that fabric.

Once that realization happens, a swim brief begins making a lot of sense.

The Practical Advantages of Swim Briefs

There are practical reasons to wear less fabric.

A properly fitting swim brief stays close to the body.

There are no wet legs flapping around after leaving the water.

There is less fabric to become waterlogged.

The legs have excellent freedom of movement.

The suit generally dries faster than substantial shorts.

And, of course, there is considerably more skin available for tanning.

But practicality is only part of the story.

Many men simply prefer how they look in briefs.

Men's Bodies Don't Need to Be Hidden

Men increasingly spend significant amounts of time working on their bodies.

They train their legs.

They develop their glutes.

They work on their abs.

They exercise, run, cycle, swim, and lift weights.

Then they go to the beach and cover everything from the waist almost to the knees.

For some guys, that no longer makes much sense.

A swim brief exposes the thighs and emphasizes the legs, hips, waist, and overall proportions of the body.

A bikini takes that idea further.

A thong takes it considerably further.

You certainly don't need an athletic body to wear any of them, but men who enjoy displaying their physiques finally have swimwear choices that let them do it.

Starting With the Classic Swim Brief

For the lifelong board-short wearer, a traditional swim brief is probably the easiest introduction.

Sometimes casually called a "Speedo," although Speedo is actually a brand, the traditional racing-style brief offers substantial coverage compared with the more adventurous styles available today.

It covers the front.

It covers the butt.

It has relatively substantial sides.

But the thighs are completely exposed.

That alone can feel astonishingly revealing to someone who has spent twenty years wearing knee-length shorts.

Then something interesting happens.

You get used to it.

The First Time Can Feel Almost Naked

Put on a swim brief at home and it might seem perfectly reasonable.

Walk onto a crowded beach wearing it for the first time and suddenly it can feel tiny.

That's psychological.

You're accustomed to feeling fabric against your thighs. Remove that fabric and your brain initially interprets the sensation as being unusually exposed.

After you've walked around, gone swimming, sat in the sun, and spent some time wearing the suit, that sensation often decreases.

Eventually the brief simply becomes your swimsuit.

And that's frequently when curiosity about even smaller designs begins.

From Swim Brief to Bikini

A men's bikini takes the basic brief and makes it more fashion-oriented.

The waist can become lower.

The sides become narrower.

The legs become higher cut.

The rear can become slightly smaller.

The front may become more sculpted.

Suddenly the swimsuit isn't merely an athletic garment.

It's beach fashion.

A bikini can make the legs appear longer and place much greater visual emphasis on the wearer's body.

Men's bikinis can also range from relatively conservative designs to extraordinarily tiny ones.

That gives a newcomer plenty of room to experiment.

The Brazilian and Cheeky Middle Ground

Not ready for a thong?

There is an entire category between a conventional bikini and a thong.

Brazilian and cheeky swimsuits reduce rear coverage without eliminating it.

Some expose only the lower portion of the cheeks. Others provide approximately half coverage.

These styles can be an ideal progression for a man who loves small swimwear but isn't certain about wearing a thong publicly.

They also illustrate how men's and women's swimwear design languages increasingly overlap.

High-cut legs, narrow sides, cheeky backs, and low rises don't inherently belong to either gender.

They're design choices.

Then There Is the Men's Thong

The thong represents a much bigger psychological jump.

The front can look similar to a bikini, but the rear coverage largely disappears.

For a man accustomed to shorts, the idea can initially seem outrageous.

For a man who has already become comfortable in bikinis, it may seem like the obvious next experiment.

And the experience is very different.

There's almost nothing covering the butt.

Tan lines become minimal.

Swimming can feel remarkably unrestricted.

And there's no pretending the swimsuit is conservative.

A thong says quite clearly:

I deliberately chose a tiny swimsuit.

For some men, that's exactly the attraction.

Men's Thongs Aren't Just for Gay Men

Thong and bikini swimwear have historically had strong associations with gay beach and resort culture, but clothing shouldn't be confused with sexual orientation.

Gay men wear thongs.

Straight men wear thongs.

Bisexual men wear thongs.

And plenty of gay, straight, and bisexual men don't like thongs at all.

A man's swimsuit tells you what swimsuit he chose that morning. It doesn't reliably tell you whom he wants to date.

That distinction is becoming increasingly important as men's fashion becomes less rigid.

Straight Men Are Discovering Bikinis Too

One of the most interesting developments in men's swimwear is that minimal styles no longer have to be treated as belonging to one particular subculture.

A straight man who likes his body might simply decide that he looks better in a bikini than shorts.

Maybe his girlfriend loves the look too.

Why shouldn't she?

Women aren't universally attracted to one type of men's clothing any more than men are universally attracted to one style of women's clothing.

Some women prefer men in trunks.

Some like swim briefs.

And some think a confident guy in a tiny bikini or thong looks fantastic.

What If His Bikini Is Smaller Than Hers?

This may be one of the most entertaining changes at the modern beach.

A heterosexual couple can arrive wearing bikinis—and his might actually be smaller.

There is nothing inherently wrong or strange about that.

For decades, fashion encouraged women to expose more of their bodies while encouraging men to cover theirs.

Modern swimwear gives couples permission to ignore that old formula.

Maybe she wants a full-coverage bikini and he wants a thong.

Maybe they both want thongs.

Maybe she wears shorts while he wears a micro bikini.

Swimwear doesn't need to enforce gender rules.

Better Tan Lines Are a Major Attraction

One of the simplest arguments for smaller swimwear is tanning.

Board shorts produce enormous tan lines.

A traditional brief dramatically reduces them.

A bikini reduces them further.

A thong virtually eliminates rear coverage.

For someone who spends a lot of time outdoors, that difference can become a major reason for choosing smaller swimwear.

Minimal tan lines are also one reason some men who initially buy a tiny swimsuit purely for tanning eventually start wearing it as their regular beach suit.

Spandex Changed What Is Possible

Modern stretch fabrics are another important part of this evolution.

Swimwear doesn't need huge quantities of material to remain secure.

High-quality stretch fabrics can conform closely to the body, allowing designers to experiment with narrow sides, high legs, small fronts, and minimal backs.

That has produced an extraordinary spectrum of men's swimsuit designs.

At one end is the conventional swim brief.

At the other are tiny micro and ultra-micro suits.

Between them are dozens of possibilities.

Micro Swimwear Pushes the Idea Further

Once you accept that a man doesn't need shorts, another question naturally follows:

How much swimsuit does he actually need?

Micro swimwear explores that question.

A micro bikini reduces the dimensions of a conventional bikini. The sides may become strings. The front may become extremely compact. Rear coverage can range from a small Brazilian panel to a thong or G-string.

Ultra-micro designs push minimalism further still.

These styles remain adventurous rather than universal beachwear, and local rules and venue expectations matter. But their existence demonstrates just how far men's swimwear design has expanded.

You Don't Have to Keep Going Smaller

There's no requirement to progress from board shorts all the way to a thong.

A man might try a traditional brief and decide:

This is perfect.

Another may fall in love with bikinis.

Someone else may prefer Brazilian designs.

And another guy may eventually have a drawer filled with thongs and micros.

The objective isn't to reach the smallest swimsuit possible.

It's to discover what you enjoy wearing.

A Simple Progression for the Curious

For a man who has spent his entire life in shorts, the transition can happen gradually:

Board shorts → short trunks → square-cut swimsuit → traditional swim brief → bikini → Brazilian/cheeky brief → thong → G-string → micro.

You can stop anywhere along that progression.

You can also skip steps.

There isn't a test.

Choosing Your First Swim Brief

Fit matters enormously.

A swimsuit should be snug enough to stay securely positioned in the water without becoming painfully tight.

Look at the leg openings.

Check the waistband.

Make sure the front provides the amount of coverage and support you want.

Then move around.

Sit.

Walk.

Bend over.

Swim if possible.

A swimsuit that looks fantastic while you're standing in front of a mirror still needs to function when you're actually at the beach.

Choosing Your First Bikini

If you're comfortable in a brief and want something smaller, start experimenting with side width and rise.

A bikini with one- or two-inch sides can feel significantly different from a conventional racing brief without being extremely revealing.

Then you can try string sides or a lower front.

You may discover that you actually prefer a smaller suit because it moves less and feels more natural.

Choosing Your First Thong

The biggest adjustment with a thong is often psychological rather than physical.

Wear it privately first.

Walk around.

Sit down.

Make sure the front provides secure coverage and that the rear strap is comfortable.

Then choose an appropriate beach or resort for your first public outing.

Some beaches are extremely accepting of thong swimwear; others are considerably more conservative. Rules and local norms vary, so checking the venue beforehand is sensible.

Confidence Changes Everything

The first few minutes are usually the hardest.

You walk across the sand and imagine that absolutely everyone is staring at your swimsuit.

Most people aren't.

Some will notice.

A few may look twice.

Someone may even compliment you.

Then you put down your towel, go swimming, talk to your friends, and start enjoying the beach.

That's when the swimsuit stops being an event.

It becomes clothing.

Men Don't Need Permission to Wear Less

Perhaps this is the biggest change happening in men's swimwear.

Men are realizing they don't have to justify wanting to look attractive at the beach.

Women have enjoyed an enormous range of expressive swimwear for generations.

Men can have that freedom too.

A man can choose something athletic.

Something conservative.

Something sexy.

Something colorful.

Something feminine.

Something masculine.

Something barely there.

Or ordinary board shorts.

The point is having the choice.

From Shorts to Briefs—and Sometimes Much Further

The movement toward smaller men's swimwear isn't really about declaring war on board shorts.

Shorts aren't disappearing, and they remain the right choice for millions of men.

What's disappearing is the idea that shorts are the only respectable choice for men.

Today's male beachgoer has an increasingly broad wardrobe available to him.

Swim briefs.

Bikinis.

Brazilian cuts.

Thongs.

G-strings.

Micros.

And countless combinations in between.

Recent men's fashion coverage has likewise pointed toward shorter, more intentional silhouettes, while enthusiast surveys suggest growing willingness among their audiences to experiment with thong swimwear.

The New Men's Beach Wardrobe

Men's swimwear is becoming less about covering the body and more about choosing how you want to present it.

For some men, that means leaving board shorts behind for the clean athletic look of a traditional swim brief.

For others, it means discovering the sexier lines of a bikini.

Some eventually decide that the freedom and minimal tan lines of a thong are exactly what they wanted.

And a particularly adventurous group will continue exploring micro and ultra-micro designs.

There is no single destination.

That's the exciting part.

The modern men's swimsuit drawer doesn't have to contain three nearly identical pairs of shorts anymore.

It can contain shorts and briefs.

Bikinis.

Thongs.

Micros.

Whatever makes the wearer comfortable and confident.

And for many men who finally make that first move from shorts to a swim brief, one question inevitably follows:

Why did I wait so long to try this?
