The Fitting Room Struggle: Why Finding a Bikini With a Large Bust and Small Band Size Is So Hard

By the founder of Via di Gioia

You know the feeling.

You walk into H&M or Zara, and there it is — a super cute bikini top. Your friend grabs her size without thinking twice and throws it in the basket. So you grab a size that has the possibility of fitting. You head to the fitting room. You try it on.

And it doesn’t fit.

So you size up. Now it covers your chest — but the back is too loose, the band is riding up, the straps are crawling toward your neck no matter how many times you adjust them. You’re standing under those fitting room lights thinking: this sucks. Is it me? Is something wrong with my body? Why is finding a cute swimwear top that fits so hard for me?

I’ve stood in that fitting room more times than I can count. I know exactly how it feels. And I want to tell you something I wish someone had told me years ago:

It’s not you. It was never you.

Why Sizing Up Doesn’t Work

Here’s what most women don’t know: in swimwear and lingerie, cup size is relative to band size. A D cup on a 75 band is a completely different size than a D cup on an 85 band. When you have a small back and a large bust, you need a small band size and a large cup size — for example, a 70F or 65G.

The problem is that fashion stores don’t work this way. They size swimwear as XS, S, M, L, XL — or they offer cup sizes A through D. So if you have a larger bust, you size up. But sizing up means a bigger band, which means no support, no structure and a bikini that rides straight up your back the moment you move.

You weren’t doing anything wrong. The sizing system was simply never designed for your body.

Why Triangle Tops Often Don’t Work Either

Maybe you tried the triangle top. It’s adjustable, after all — it ties at the neck and the back, so surely it can work for any size?

The truth is, a triangle top is designed for smaller busts. The thin halter straps are sexy, but if they need to carry a lot of weight, they will cut into your skin. Same goes for the straps that go around your rib cage. Loosing up the halter straps won’t work either, because that means you’ll loose the support you want. So you keep moving the knot in your neck to ease the pain, leaving you adjusting all day and never quite feeling secure.

And Then There’s the Specialised Lingerie Store

So you give up on the fashion store and head to the specialist lingerie shop around the corner. They have your size — finally. But when you look at the swimwear on the rack, your heart sinks. The designs are outdated, matronly, built for a different generation. Nothing that feels like you. Nothing that feels young or fun or beautiful.

And so, for the hundredth time, you leave with nothing. Or worse — you leave with the bikini that fits but makes you feel invisible.

The Real Problem

For years, I watched my friends grab beautiful bikinis off the rack without a second thought. And for years, I stood in fitting rooms feeling like my body was the problem. Like I was too complicated.

But the truth is simpler and more frustrating than that: the swimwear industry has never designed for us. Women with a small band and a large cup size have been an afterthought — or not a thought at all. The market gap isn’t a mystery. It’s a choice the industry made, over and over again.

You’ve been choosing between two options that are both wrong. A bikini that’s cute but doesn’t fit. Or a bikini that fits but isn’t cute. That’s not a choice. That’s settling.

This Is Why I Started Via di Gioia

I’m the founder of Via di Gioia, and I was that woman in the fitting room. For almost ten years, I searched for swimwear that had four things: my size, a beautiful design, sustainable materials and ethical production. I never found it.

So I decided to make it myself.

Via di Gioia is a swimwear brand that started for women with a small band and large cup size — but we design for every woman. Whether you have a small, medium or large bust, a narrow or wider back — we offer beautiful, creative designs in a full range of sizes and fitting styles. Every top comes in three fits: balconette, plunge and triangle. Every bottom in four: high-waist, V-shape, classic cut and tanga. Because bodies are different, and your swimwear should actually reflect that.

And because we believe that taking care of the planet and the people who make our clothes should be the norm — not the exception — every piece is made with sustainable materials and ethical production.

We started Via di Gioia for the woman the swimwear industry forgot. But we believe beautiful, ethical swimwear should be for every woman. So while our heart is with the small band, large cup community — everyone is welcome here.

You’ve been wearing the wrong size for long enough.
