If you buy something through a link in our posts, we may get a small share of the sale.

​For larger busted women, keeping the girls comfortably in place for a day at the beach or pool is no simple feat. As a matter of fact, it can be nearly impossible, and really can impede what would otherwise be an enjoyable day.

Many women in this situation consider wearing a bra under their swimsuit, but we’re here to tell you that is not a good idea. However, you don’t have to ditch the idea of looking sexy in your swimwear. We’ll walk through the reason why you don’t want to wear a bra under swim suits, and give you several options to utilize instead.

Best Bra To Wear Under a Swimsuit

​If you elect to wear a bra under your swimsuit, then there are several things you need to pay attention to. We actually think there are better options in general, which we go into detail below. But, if you opt to go the route of a swimming bra, here are some considerations:

  • ​Opt for a sticky bra: ​You’ll need to opt for a backless bra if you’re wearing one in a swimsuit. Because of that, your only real option is to turn to something with adhesive. 
  • Opt for a silicone bra: ​Getting a bra wet is tricky business. Obviously anything with cotton or padding won’t work, plus, you’re going to need to wash them well afterwards. ​So what material will? Silicone is pretty much the only option when it comes to wearing a bra in salt and chlorinated water. 
  • Don’t go cheap: ​Cheaper sticky bras lack the staying power that a nicer one has. The last thing you want is the adhesive to come “un-stuck” half way through the day or, even worse, while you’re out frolicking in the waves.
  • ​Come up with a long term solution: ​Over the long haul, its probably better if you have several options for swimsuits. Perhaps you want to hang out to that super cute bikini and where a silicone bra with it. But, you will also want a swimsuit that requires a little less work sometimes. 

We recommend the Silicone Lift Bra from Fashion Forms. It has fantastic adhesion and stick, and comes in sizes B-H.

Best Swimsuits with Built-In Bras

Another option to consider is to buy a swimsuit that already takes care of your problem. Rather than try to find a bra to wear under your suit, you can opt for a bathing suit that has a built in bra. Here are our favorite selections.

​Why Wear a Bra Under Your Swimsuit

First, lets look at the main reasons why someone might want to put a sturdy, supportive bra on under their bikini or swimsuit.

1. Not Enough Support

Yes, its true… many to most bathing suits don’t offer a good deal of support. Whether it be as a result of flimsy material, thin straps, or small cups, swimsuits are notorious for putting looks ahead of support.

And why would they? Lets be honest – summer should be chock full of long days in the sun with family and friends, enjoying the beautiful weather and showing off what you have to offer.

Fashion styles these days are full of free flowing bralettes, seemingly made for ladies that don’t need a healthy dose of support for their boobs.

However, a bathing suit with no support is no day in the sun, and can be really uncomfortable. Luckily, there are lots of bathing suit options for supporting large busts.

​2. Nipple Shows Through

It’s not just you – there are a whole host of reasons that nipples show through in a bathing suit, even when this typically isn’t a problem for you in your everyday bra.

For starters, your body is typically going through a lot more temperature fluctuation as you go in and out of the water. Needless to say, this can cause nipples to get a little harder… and a lot more noticeable.

Some of the trendier bathing suit options these days opt for material that covers your skin nicely, but can leave a little bit to be desired when it comes to nipple coverage.

Sometimes it isn’t that the nipple is prominent, but just that you can see the bump that exists in the region. No matter what the reason, its not abnormal for this to be a situation you deal with.

This is also a problem experienced by ladies looking for a good swimsuit for smaller breasts. Big or small, nipples can easily show through a suit.

Picking bathing suit tops that have padding will help this problem a lot. There are also a lot of DIY solutions, just in case you want to wear that ultra-cute suit that you know leaves you showing a bit.

Should You Wear a Bra Under a Swimsuit?

​Never wear a regular bra under your swimsuit – it will ruin it. If you must wear a bra under the suit, make sure to wear one specifically designed for it.

Generally speaking, though, its better to find a better option for your boobs and swimsuit that opting for a bra. There are a variety of reasons, and we’ll go through each quickly:

  • There isn’t room: Bathing suits and bikinis are form fitting, and designed to be worn tight against your skin. A bra will cause bulge and odd-looking bumps. This will put a damper on your margarita sipping summer times.
  • Your bra will show: No matter how hard you try, your bra will end up showing at some point throughout the day. Whether it’s the straps or the cup, its only a matter of time.
  • Wrong material: Swimsuits are made from fast drying, synthetic material that is designed to wick water and dry quickly. Bras, on the other hand, are typically made from thick cotton and padding. They do not dry quickly, and will actually stay wet the entire time you have your suit on. (Even silicone bras don’t dry the same way as your suit, sometimes leaving you with “wet boobs”.
  • Chlorine and Salt Water: Bathing suits and swimwear is made with material that can handle the damaging chlorine and salt water that a pool or ocean will throw at your. Your bra, on the other hand, will break down and wear away from these properties.
  • Uncomfortable: At the end of the day, you’ll just be uncomfortable. Bras are not designed to be worn under a bathing suit, and there are a variety of reasons that it will just be flat out uncomfortable. Whether sand or movement, you’ll regret trying to make it work.

How to Avoid Needing a Bra Under a Bathing Suit

Ok, lets talk what to look for in a bathing suit that does not need a bra underneath it! Typically we’re talking to the bigger girls out there, and so you’re going to be looking for more support and shape to help your pair.

  1. Padding: Plenty of bathing suits are made with padding, designed to help pad your breasts in a suit. This can come in a variety of forms, from silicone and foam padding as a part of the suit, or removable pads that you can add in. Ironically enough, you can also look at pushup bikinis for more shape and support.
  2. Sturdy bands: This can be a little tougher, as sturdy bands are often synonymous with a swimsuit that lacks sex appeal. Don’t be dismayed though, you can find great options with sturdy bands. One tip is to look for a bikini that is more of the tankini style, rather than opting for larger straps to hold up your breasts.
  3. Underwire: Yes, bathing suits come with underwire, should you want them. While the debate between underwire and no underwire will also live on, they can be a huge asset in a swimsuit. And that little bit of wire might be all the support you need.
  4. Cup Material: Soft cups made of thick fabric can help give you boobs shape, while also giving you support and protecting your nipple from showing. Sometimes referred to as foam cups, shaper bra cups, and molded bra cups, these are a must for bigger busted women.
