Understanding Swimsuit Bra Tops


Bra top swimsuits combine the support and comfort of a bra with the style and functionality of a swimsuit. Bra top swimsuits are ideal for women looking for bust support, large-busted women, and women who have undergone mastectomy treatment. From underwire tops, to padding and cups, this guide will cover everything you need to know before choosing a swimsuit bra top.

Bra Top Styles

Built-in bra tops can be found in many swimsuit styles including bikini tops, tankini tops, and one-piece suits. Bra tops are supported with horizontal elastic strips, molded cups, or underwire. Boning in a swimsuit top refers to a plastic or metal seam placed in the side of the suit that provides additional structure and support. This is commonly found in bandeau and strapless tops.

Underwire Bra Tops

Most bra tops include an underwire and padding combination. Underwire bras are built with sewn-in wiring that is placed in a U-shape underneath the breast. The wiring can be made out of metal, wire, or molded plastic. It is designed to provide support, lift, and separate the breasts.

Hidden underwire does not use a seam to separate the cups from the underwire. It provides a smoother and more natural appearance than a traditional underwire top. Hidden underwire is commonly found in tankini tops and one-piece suits.

Bra Top Cups

There are various cup styles used in both underwire and non-underwire swimsuit bra tops. Underwire with sewn-in soft cups uses a built-in fabric to smooth and shape the bust. Underwire with removable soft cups allow the wearer to add or remove the fabric insert. Underwire with sewn-in soft cups and prosthesis pockets are used in post-mastectomy swimwear. It is designed to allow a prosthesis form insert to be placed inside the breast pocket.

A soft cup top is a molded cup that does not use metal or hard plastic to support the bust. Instead it relies on a thick band of fabric, underneath the bust, to provide support for the wearer's breasts. Soft cups hold their shape while smoothing, supporting, and covering the breasts. These are also referred to as molded bra cups, shaper bra cups, and foam cups.

Padding vs. Push-up Bra Tops

Padded bra tops refer to tops that use silicone or foam padding to add size and shape to the breasts. These can also come with removable padding. Push-up bra tops place padding on the bottom/outside of the bust and is designed to push the breasts up and inward to create instant cleavage.

Padding and push-up bra tops can come in both underwire and non-underwire tops. Padding and push-up pads can also be purchased and inserted into the underwire top or placed inside sewn-in pockets.

Top it Off

The swimsuit's sizing depends mainly on the brand and style. Some bra tops are sized based on the bra size, cup size, or standard swimsuit sizes. Make sure to find a bra top that fits you in both style and size. Whether you're search for support, cleavage, or smoothness, there are many options to choose from at SwimOutlet.com.

I am looking for a two piece suit that I can wear in an upcoming triathlon. I need a top that will offer support both in the pool and out of the pool while running. What do you recommend?

I purchased one of your rashguards and I love it in the pool, however there is not much support. I am looking for a sports bra-type swim top to go underneath. What do you recommend. I can't tell which sports bras that you sell can be worn in water.

Do you carry any one piece suits with shelf bras at all? Every time I try cup bras they're either too big (I'm smaller on top than on bottom) or the cups come below my breasts. I can already see that I'm a statistical outlier since I'm barely a C-cup and that's just because I'm very overweight.

I have a double mastectomy (unreconstructed) and swim laps three days a week. I have been wearing a Speedo with a shelf bra or cutting out the padded soft cups. Now I am going to a beach resort. I do not even own a prosthesis for the left side and do not want to wear any for snorkeling. I am a size 20 W and in my 60s. Any help?

Hi, I'm just a girl looking for a bikini that stays on and is totally dive proof, swim proof, and action proof! I'm tired of flimsy bikinis with foam cups that slip out or get mangled by the waves, but I don't want to sacrifice getting a full tan by wearing a one piece. Oh and bottoms that stay on tight with no pesky strings would be great too! Hope you can help!

I am in the same boat. I am a 40F. I have been hunting for a decent suit since last spring (2014). I have a generic one piece, but hate the way it fits, feels and looks. I was hoping to find a bra sized tankini, but no luck. I have done more google searches than I can count. Most places that boast plus size suits size in the standard 18W or XL type sizes. They If they tell you anything about what bra size that actually fits you will find that most only go to DD. The same is true of places that do bra size suits - much like this site. There are a few sites I have found that do carry 40F or higher. Most need to be converted to UK sizes. Most of the also are true bikinis or "sexy" tankinis. Neither of which cover or support much of anything. They also cost nearly $100. Even Lane Bryant doesn't carry anything that I have been able to wear. There is a place called Lind's out of NYC that seems to have some good choices, but sales are final and I can only access it online. Not gonna happen. So much for specializing in plus sizes. If you find anything, PLEASE let the rest of us know.

Just a thought for those of you having trouble finding suits with a good fit. Maybe looking through some sewing blogs would help. You may be able to find someone who is skilled at bathing suit and/or bra sewing (and fitting) who could make you a custom suit. Etsy.com would be a good resource for that as well. Many people learn to sew to solve fit issues with ready-to-wear clothing, but even if you don't sew, you may be able to find someone else who does who would be willing to make you what you are looking for.

Do you know her actual bust measurement? It would be the measurement around the fullest part of her bust. You can match that up with our measurements from our sizing charts. I hope this information is helpful. Please let us know if you have any questions. Have a wonderful day!

Hi Tracy,

We would be happy to help you with sizing. Sizing depends on the suit you're looking at. If its a competition suit then the sizes run by the bust measurement. If its a fitness suit then it runs by the womens dress size. We also recommend taking your bust, hips, and waist measurements and comparing them to our size charts. Below is a link to our size charts. Please contact us again if you have any further questions. Have a wonderful day!

Is it okay to order a size larger than you are to compensate for the bust or is it better to just order true to size ?

I am looking for a wireless bikini top, I measure 48 across fullest part of my breast. I usually wear 40G bra. It is hard to find a top that keeps the girls in place but allows me to get sun by the pool and swim also. I have tried wired and they rub and jab in all the wrong places.

What is it called when a swim suit has an adjustable back band just like a bra? I know they exist but have a hard time locating them online because I don't know the description I should be using.

Hi Jenny,

You can try a search for hook and eye clip swimsuits. Or try adjustable straps. It doesn't look like we carry any that have the hook in the back. Most of our adjustable back straps are tie backs. I hope this information is helpful. Please let us know if you have any other questions. Have a wonderful day!

Hello. I am looking for a lap-swim, one-piece suit--I am a 36D and would like a sporty looking suit (not frumpy i mean!) that also has good support. Any suggestions? I like the look of the Aqua Sphere suits but can't tell if they have any with a bra-like insert. Shelf bras usually aren't supportive enough. Thanks

Hi Chris,

Below is a link to suits that have soft cups in them. Usually if a suit has extra support like a shelf bra or soft cups, it will be noted in the description. You should be able to find these types of suits in the Fitness section. I hope this information is helpful. Please let us know if you have any questions. Have a wonderful day!

Hi Zachary,

What kind of suit was she looking for? A one piece or 2 piece? She would probably want a suit that has some support so anything with cups or shelf bras. Below is a link to our section for d cup and up suits:

Hi Danielle,

Congratulations on your marriage! Unfortunately we do not have any tankinis that go up to a 40G. Do you know the actual measurement around the fullest part of your bust in inches? I can see if we have something else that may fit you. As for the boardshorts, below is a link to our boardshorts that come in plus sizes:

DD swimsuits and bras do not seem to be the same size ever! I wear a 42DD bra, but when I order a DD swimsuit top, it is wayyy too small. What is the largest top you have? I have a DD I need to return, but would love to just swap it for one that fits!

I always hated the fact that my DD size forced me into 'plus size' swimwear, when I wear a size 10-12! :) Love the one piece I got from you all, though I had to get a larger size to fit my bust.

Hi Debra,

Hi Monet,

Congratulations on your new bundle of joy! Unfortunately we do not carry any suits or tops in F-Cup sizes. I'm sorry! I would suggest maybe looking for a tankini top for coverage and style. The tankini tops we have in the link below only go up to size DD:

http://www.swimoutlet.com/Fashion_Tankinis_s/558.htm

You may want to try a Google search for Tankini tops in F-Cup sizes. You should be able to find something out there. Good luck!
