You’ve packed your sunscreen, found the perfect swimsuit and are ready to hit the beach or pool — but then the thought hits you: “Should I wear a bra underneath?”
It’s one of those little questions that pop up just before a swim. And the answer isn’t always a straight yes or no — it depends on your comfort, your swimsuit’s design and how much support you need. Let’s break it down together.
When and Why You Might Wear a Bra Under Your Swimsuit?
If your swimsuit feels a bit too relaxed around the bust or doesn’t give enough lift, wearing a bra underneath might help. Some women like that extra support, especially during active days — think pool laps, beach games or water workouts.
In that case, a non-padded, wire-free bra works best. It gives you gentle support without adding bulk or creating odd outlines. Avoid removable padding bras because those pads can shift or crumple once wet — and no one wants that discomfort mid-swim!

If Not a Bra, What Are the Alternatives?
If layering feels like too much, don’t worry — there are plenty of clever options. Many swimsuits now come with built-in support like elastic under-bands, moulded cups or shelf-bra designs that keep everything in place.
You can also try wearing a bralette-style bikini top, which gives a similar soft hold but is made for water. (If you’re new to swimwear and want to understand the basics, check out our What Is a Bikini? guide — it’s a great place to start.)
How to Avoid Awkward Lines or Bulges?
If you decide to wear a bra under your swimsuit, the trick is keeping it invisible. Go for a smooth, seamless finish with thin edges. Match the bra colour to your swimsuit and make sure the straps sit neatly underneath.
Do a little mirror test before stepping out — move around, raise your arms or bend slightly. If nothing shifts or shows through, you’re good to go!
Can You Go Bra-Free?
Yes, you can — and many women do! If your swimsuit fits well and gives good support, you don’t need to wear a bra underneath. One-piece swimsuits, tankinis and good-quality bikini tops are designed to keep you comfortable and secure. You’ll feel lighter, move easily and dry faster too — simple and comfortable!
What If Your Swimsuit Doesn’t Offer Enough Support?
If your swimsuit still feels a little too loose or unsupportive, you have options.
Try a swimsuit with a built-in shelf bra or wider straps for added lift. You can also wear a thin non-padded bra underneath as long as it doesn’t cause lines or discomfort. And remember — the right fit is everything. Even the prettiest swimsuit won’t feel good if it’s too big or too tight.
Do You Need a Swimsuit to Swim, or Are Shorts and a T-Shirt Enough?
You can swim in a T-shirt and shorts, but it’s not the best idea. Regular clothes soak up water, get heavy and make it harder to move around. Swimsuits are designed to stretch, fit well, and dry quickly — they also stay in place while you swim. So, while casual wear is okay for a quick dip, a proper swimsuit is the smarter and more comfortable choice.
In the end, there’s no one right answer — it’s all about what makes you feel comfortable.
If you like extra support, wear a non-padded, wire-free bra under your swimsuit. If your swimsuit already feels supportive enough, skip the bra and enjoy the freedom.
Whether you’re relaxing by the pool or going for a swim, feeling confident and comfortable is what really matters.
