It happened at a beach club in Ibiza, then a red carpet in Los Angeles, and now it’s basically every third person at your local music festival. We are talking about side boob in public. It’s that specific sliver of skin revealed by deeply cut armholes or strategically loose tank tops. It’s everywhere.
Honestly, fashion is weird. One year we are all wearing turtlenecks and the next, the industry decides that the lateral view of the ribcage is the most important real estate on the human body. This isn't just a "celebrity" thing anymore. It has migrated from the high-fashion runways of Saint Laurent and Valentino directly into the aisles of Target and onto the racks at H&M. But here is the thing: wearing side boob in public isn't just about picking out a shirt. It’s a logistical nightmare involving physics, double-sided tape, and a weirdly complex set of social "unwritten rules" that seem to change depending on which zip code you’re standing in.
Some people call it empowering. Others call it a wardrobe malfunction waiting to happen. Most people just want to know how to pull it off without getting kicked out of a brunch spot.
The Evolution of the "Side-Eye" Silhouette
Fashion historians—yes, that is a real job—often point to the early 2010s as the modern rebirth of this look. Before that, it was mostly a relic of 1970s surf culture. Think of those old-school muscle tanks that were basically two strings held together by a prayer. But the 2020s have taken it to a whole new level.
Why now? Well, the "no-bra" movement (often tagged as #FreeTheNipple on social platforms) really paved the way. Once people started prioritizing comfort and natural silhouettes over the aggressive padding of the early 2000s, the side boob in public look became a natural byproduct. It’s low-effort but high-impact. It says, "I just threw this on," even if you actually spent twenty minutes positioning "boob tape" to ensure nothing actually slips.
The trend has been heavily influenced by what we call "festival core." Places like Coachella or Burning Man are basically testing grounds for how much skin the general public is willing to tolerate. Once a look survives a weekend in the desert, it usually finds its way into the suburbs about six months later.

The Physics of Staying Covered
Let’s get technical for a second. If you’re going to rock side boob in public, you’re dealing with the laws of motion. Gravity is not your friend here.
Most people think they can just wear a loose tank top and be fine. They are wrong. You lean over to pick up a latte? Disaster. You reach up to grab something from a shelf? Double disaster. To actually pull this off, most stylists recommend a three-tier approach. First, there’s the garment choice. Fabric weight matters. A heavy cotton will stay in place better than a flimsy silk.
Then there is the adhesive. Ask any stylist who works with A-listers like Florence Pugh—who has basically become the queen of the daring silhouette—and they will tell you that fashion tape is the unsung hero of the red carpet. Brands like Fearless Tape or Hollywood Fashion Secrets make double-sided strips that literally glue the fabric to your skin. It sounds painful. It kind of is when you take it off. But it’s the only way to ensure that "side boob" doesn't turn into "full frontal" when you’re walking down the street.
Lastly, there’s the posture. You can’t slouch. Slouching creates gaps. You have to walk like you have a string pulling the top of your head toward the ceiling. It’s a workout.
Social Etiquette and the "Appropriateness" Debate

There is no universal law, obviously. But there is a massive gap between what is acceptable at a beachfront bar in Miami versus a grocery store in a quiet suburb. Context is everything.
- The Beach/Pool: Total free-for-all. Side boob is the standard here.
- Music Festivals: Expected. If you aren't showing a bit of ribcage, are you even at a festival?
- Casual Dining: This is the gray area. Outdoor seating is usually fine. High-end indoor dining? You might get some looks from the staff.
- The Workplace: Generally a no-go. Even in "creative" offices, the side boob in public look is usually seen as a bit too casual (or distracting) for a 9-to-5 environment.
The debate usually centers on "modesty" versus "body autonomy." Critics argue it’s "too much," while proponents argue that skin is just skin. Interestingly, a 2023 survey on fashion trends showed that younger generations (Gen Z and younger Millennials) don't even see side boob as "provocative" anymore; they see it as a structural design element, like a cutout or a high slit in a skirt.
The Celebrity Influence: Who Started This?
We can’t talk about this without mentioning the people who made it a "thing." Rihanna is the undisputed heavyweight champion of the daring side-silhouette. She’s been doing it since the "Umbrella" era. Then you have Miley Cyrus, who took the 70s rockstar aesthetic and ran with it.
But it’s not just the "edgy" celebs. Even more traditionally "polished" stars have adopted it. When Anne Hathaway showed up to a Valentino show in a dress that was basically two pieces of fabric held together by hope, the internet nearly broke. It signaled that this look had moved from "rebel" to "high fashion."
However, celebrities have an advantage: they have handlers. They have people checking their tape every five minutes. When you’re just a regular person trying to navigate side boob in public while catching a bus, you don’t have a glam squad. You have your own reflection in a shop window.

Risks and Reality Checks
Let's be real. There are risks.
Sunburn is the one no one talks about. You apply sunscreen to your arms and your chest, but you always forget that weird little crescent of skin on your side. Result? A very specific, very painful red mark that looks like a comma.
Then there’s the "creep factor." Unfortunately, showing more skin often results in unwanted attention. It sucks, but it’s a reality of navigating the world today. Many women report that while they love the look for themselves, they often carry a "cover-up" shirt or a light cardigan just in case they feel uncomfortable in certain environments.
And let’s not forget the sheer physical discomfort of some of these tops. If the armhole is cut too high or the fabric is too rough, you’re looking at serious chafing. It’s not all glamour. Sometimes it’s just itchy.
Actionable Advice for Rocking the Look
If you’re planning to head out with the side boob in public look, don't just wing it. Follow these steps to keep things stylish and avoid a literal exposure scandal.
- Invest in "Pasties": Even if the top is thick, cold weather happens. Silicone covers are a lifesaver. They provide a smooth silhouette and a bit of extra security if the shirt shifts.
- The "Mirror Test": Don't just look at yourself head-on. Turn 90 degrees. Bend over. Reach for the sky. If you see more than you’re comfortable with in your bedroom, you’ll definitely see more than you want at the mall.
- Fabric Choice Matters: Look for structured fabrics like denim, heavy linen, or thick knits. Avoid "slinky" synthetics unless you are prepared to tape every single inch of the garment to your body.
- Layering is Your Friend: You can do a "soft" version of this trend by wearing a lace bralette or a decorative bandeau underneath. It gives the same vibe without the constant fear of a wardrobe malfunction.
- Know Your Audience: It sounds old-fashioned, but checking the "vibe" of your destination saves a lot of awkwardness. If the place has a dress code, the deep-cut tank might stay in the closet.
The "side boob" trend isn't going anywhere. It’s a staple of the "naked dressing" movement that has dominated the mid-2020s. Whether you love it or hate it, it’s a masterclass in how fashion can take something tiny—a few inches of skin—and turn it into a massive cultural conversation. Just remember: tape is your best friend, and sunscreen is a non-negotiable.
To make the most of this trend, start with a "moderate" cut. A top where the armhole drops just a few inches below the standard line allows you to get used to the feeling without the high stakes of a deep-plunge side. Once you're comfortable with the logistics, you can move toward more daring cuts. Always keep a few emergency safety pins and a fresh strip of fashion tape in your bag to handle any unexpected fabric shifts throughout the day.
