Getting Better Support By Wearing a Bra Under Swimsuit

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 using a bra 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.

Our Top Bras To Wear Under a Swimsuit Reviews

​If you elect to wear a bra under your bathing suit, 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 your bra well afterwards. ​So what bra material will? Silicone is pretty much the only option when it comes to wearing a bra under a bathing suit in salt and chlorinated water. 
  • Don’t go cheap: ​Cheaper sticky bras lack the staying power that a nicer bra 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 years, it’s probably better if you have several options for swimsuits. Perhaps you want to hang out in that super cute bikini and wear a silicone bra with it. But, you will also want a bathing suit 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.

Another option to consider is to buy a bathing suit 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 one in it, like a built in bra. Here are our favorite selections. 

Two Piece

If you’ve been stuck searching for a bikini that has an adequate support for your breasts but still looks super cute, this is our choice.

First off, let’s talk about the support. This Attraco Two Piece Swimsuit adds a built in soft shell bra to this two piece swimsuit.

The one is made from a combination of polyester and spandex and incorporates elastic to hold you in place. 

There are several different versions of this suit, so you can style according to your preferences.

We find this to be a great option for larger busted women who want to look cute in a two piece but need a modest yet attractive top. 

Sporty One Piece

This stylish and sporty one piece, the Speedo Endurance+ is great if you’re looking for a swimsuit you can be active in similar to a sports bra, while still having built in support for your breasts. 

Specifically, Speedo incorporates their Hydro Bra into the suit, and it does wonders to keep everything in place.

The cups are removable, allowing you to customize the support you get, depending on the situation you’re in. 

This swimsuit does not come with any underwiring, if that’s a concern for you. The bra is completely mesh and elastic. 

With Core Compression by Speedo, you’ll get the benefit of strategically placed mesh that helps slim and trim you out as well.

Halter Top

When you choose a halter top, the strap goes around the neck. It normally provides triangle cups and thicker straps for more coverage.

Even if you are a big-busted girl, you can enjoy both padded and non-padded versions. 

Furthermore, a halter swimsuit aims to slim your body and hug your curves, unlike other swimsuit tops. It makes use of center-pull straps to lift the bust, which is a good alternative if you don’t like wearing bras with underwire.

The push-up design flatters a lady’s figure while still offering flawless bikini style. 

For instance, the SHEKINI Women's Halter Bandage Bikini takes advantage of a crisscross front detail, adjustable spaghetti strap, and tie at the neck and back to hold the breasts.

It also provides padded cups for good comfort. Since everything is adjustable, you can control the degree of tightness and comfort.

Bandeau Bathing Suit

Show more skin without sacrificing support with the help of bandeau bikinis! A bandeau refers to a garment that wraps around a lady’s breasts. With this style, you can enjoy several features such as wire-free, stretchable, removable straps, tie-on styling, and front knot tie. 

A great option is the ZAFUL Women's Lace-up Bandeau Bikini, which is a strapless bandeau that offers the classic crop look.

The one has an adjustable back-strap design, which means you get to adjust the tightness to feel more comfortable in the chest. Even if you have a small bust, you can adjust the top strings to make the bandeau tighter. 

Since this bandeau bikini has a double-lined stretchable material, you can ensure you’ll find the right size for you.

While there isn’t any padding, the material itself is pretty thick. Form flattering and super comfortable; you won’t even feel weird that there are no shoulder straps.

A longline is a bikini top that extends down to the hips or waist. However, this means you need to check how the bikini fits the waist.

A longline bra should feel snug and firm to let you know if it’s capable of doing its job of supporting properly.

If you need to get an extra-wide band to provide more support, you’ll find longline bikinis more suitable for your bust. Some have underwires that guarantee optimal bust support.

Depending on your needs, you may look for a longline bikini with a firm control in the stomach for shaping. 

For example, the LALAGEN Women's High Waist Bikini flaunts a wide band that provides more coverage and support. With the addition of an adjustable buckle and detachable shoulder strap, you can adjust the straps to the suitable length you need.

What’s more, there are breathable underwire cups for more support while helping your body retain enviable shape.

Multiway Bikini Top

When you’re investing in swimwear, you’ll want to consider flexibility and versatility. With multiway bikini swim tops, you can create several designs while using a single bra. Strap configuration may depend on your bust size, preference, or presence of hooks. 

Also known as convertible bikini swim tops, a multiway bra is a must-have, especially since you can adjust the straps to form a halter neck, crossover back, strapless, low back, narrow front, and one-shoulder.

Try a multiway bra if you want the freedom to experiment with different styles while still getting the right amount of support of a bra. 

An excellent product choice is the Freya Women's Deco Underwire Molded Multiway Bandeau, which is a bandeau with straps that can crisscross in the front and tied around the neck.

This multiway bra offers a ton of support as a bra and coverage thanks to the foam underwire cups. Even when you get a strapless style, this supportive multiway bra will still hold the bust well. 

​Why Wear a Bra Under a Swimsuit

First, let’s question the main reasons why someone might want to put a sturdy, supportive bra on under their bikini or swimsuit.

1. Not Having A Good Deal of Support

Yes, it’s true… many to most new bathing suits don’t offer a good deal of support like a bra.

Whether it be as a result of flimsy material, thin straps, or small cups, bathing suits are notorious for putting looks ahead of support.

And why would they?

Let’s be honest – summer should be chock full of long days in the sun with family and friends, enjoying the beautiful weather as you please and showing off what you have to offer with enough support.

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 support options for large busts.

​2. Nipples Can Show Through in a Bathing Suit

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, it’s not abnormal for this to be a situation you deal with.

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

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 without a bra.

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, it’s better to save and find a better support option for your boobs and swimsuit than 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, it’s only a matter of time.
  • Wrong material: Bathing suits consist of 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 people. 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, let’s talk about 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 for support, 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 for support. 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 your boobs shape, while also giving you extra 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.

Last Words

In the end, it’s best not to wear a bra underneath your bikini or one piece.

Instead, opt for the variety of swimwear options that are available to take care of the support problem, and enjoy your days at the beach.
