Just like the Original Bralette, The Underwire Bralette offers the same great support as all of SassyBax bras. It smooths your back, while ultrasoft microfiber wicks moisture from the body. The addition of the underwire is for those times when a little extra shaping for the bust is desired. Customers often deem it “the most comfortable bra they’ve ever worn.”



  • 96% Microfiber Nylon 4% Lycra

  • Underwire for extra bust shaping

  • Wide self-adjusting strap for comfort that won't dig into shoulders

  • No bra bulge back

  • Made in USA

Feels like Heaven
Written by Martha on 1st Jun 2021

I have probably 30 Sassybax Products. I love them all. This bra has become my go to bra because it's comfortable and supportive, and makes me feel beautiful in whatever I am wearing.

First Time Fit
Written by Mary Lou on 1st Jun 2021

It's great to have a bra fits when I put it on the first time! I have tried on as many as 20 bras at one time and have none fit properly-except SassyBax.

Only bra for me
Written by Sara on 21st Nov 2020

I have worn hundreds of bras. Tried to get a comfortable bra that is supportive. This is it. No uniboob, lots of support, no back bulges, utimate comfort, quality. I stupidly try one of the other brands, both pricey and cheap. Nothing, NOTHING compares to this bra. Period.

This bra is very comfortable and provides full coverage. Would purchase this bra again!

The one and only
Written by Sunny P on 30th Sep 2020

I can't say more than the subject line. But seriously, for at least 12 years now, this is the only bra for me.

Underwire Bralette
Written by TK on 7th May 2019

I like these bras. I've had breast cancer, mastectomy, on my left breast and reconstruction on both breasts. Of course nothing fits like before the breast cancer, but I found that the underwire bralette fits better and is more comfortable than a regular underwire bra. I love the wide back smoothing support of the bralettes. I recommend either the underwire or the regular bralette. I wear both, the non underwire i use mainly to sleep or that lazy pajama day.

Very comfortable!
Written by undefined on 9th Feb 2019

I have several Sassybax bras, but this is the first underwire bralette I've purchased. I discovered that I like it a lot! So much so, in fact, that I think I'll be purchasing underwires from now on. Very comfortable for ALL day wear and into the evening.

best bra

best bra for support, separation and comfort hands down.

The only bra I wear
Written by undefined on 14th Jan 2019

I have been wearing the original bralette and the underwire bralette for many years. They are the most comfortable bras and last forever. Since I am large busted, I prefer the underwire because it separates the girls better than the original.

best bra ever

comfortable, supportive, no bulges. the perfect bra!

Great Product
Written by undefined on 14th Mar 2018

I love this bra. My sister recommended Sassybax to me after I had surgery. This bra gives me the perfect and amount of support and it is comfortable enough to sleep in.

Written by Pam McLeod-McKim on 11th May 2017

LOVE, LOVE, LOVE this bra. I normally do not wear underwire bras due to discomfort. However, I own several different styles and this bra is by far the most comfortable of all - will be purchasing another in black! Definitely my go to bra...thank you SASSYBAX for making such an AMAZING product!!

Sassybax underwire.
Written by undefined on 12th Mar 2017

Love the product. Every time I try to buy on line web site doesn't allow. Can you help me?

Been wearing the underwire bralette for years!
Written by Kathleen on 3rd Jan 2017

Thoroughly enjoy the underwire. My only suggestion would be to make the straps adjustable because after so many washings the spandex does stretch out a little. I don't think it would take away from any smoothness that the bra provides. Otherwise I give the bra five stars. Especially comfortable during the summer months. Thank you.

The Best
Written by undefined on 30th Oct 2016

I was introduced to Sassybax over ten years ago by my Dr., back then I had a breast surgery and he suggested I should wear sassybax bralette (no underwires) while I recovered, well...that's what I wear since then, I also love underwire bralette, and I have several of their tops. In my opinion they are great quality, look and feel great. I am very sensitive when it comes to wearing a bra since I have a condition that causes pain in my body, I tried every brand and spent a fortune trying to find the bra that would work for me before Sassybax, their Customer Service is Outstanding.

Goodbye Back Fat!
Written by janmarie on 6th Jul 2015

I've worn several different bras in Sassybax line. My two favorite are The Underwire Bralette and Original Bralette . They have always been SO comfortable, but something has changed! Seems the band is shorter? SASSYBAX RESPONSE Dear Jan Marie, You are correct. We shortened the band on The Underrwire Bralette ONLY (it works better for the vast majority of our customers-most thought it was too long.) The Original Bralette is EXACTLY the same as it has always been.

Expect the best

I have been trying different bras for years. Then, a girlfriend told me about Sassybax. The best decision I ever made! Bought 2, but will be ordering more!! I love this bra! Great support, and no more back fat!! YAY! Amanda's Response: Thank you for your review. We love to make our customers happy!

Why Did It Take Me So Long To Find You!!
Written by Elaine on 18th Apr 2015

I absolutely love this bra! I've worn underwires for a long time and this is the most comfortable one ever. The fit is very smooth, and of course it eliminates all those unsightly bulges cause by hook & eye fasteners. You certainly have created a wonderful product - thank you! Amanda's Response: Thank you for you kind words! We love hearing them.

Actually, pleasantly surprised!!!!!
Written by TC on 17th Mar 2015

Totally removes back fat!!! No question. My only issue is the puckering on the front! Kinda see it thru my shirt....but love everything else about it. Would definitely buy again. As comfortable a bra as I've ever worn! EVER!!M!!!! Amanda's Response: That little ruching on the front that you call puckering is due to the bra being knit not cut and sewn. That's part of the reason it's so comfy. Glad you are 99% happy! :)

Finally fits!
Written by Carolyn on 10th Feb 2015

I am small but big busted. I find this bra fits comfortably with support. I like the way it smooths my back and under my arms but doesn't feel like i have amour on! Amanda's Response: Very cool! So happy that you like it!

What backfat?
Written by Terri on 6th Aug 2014

Can you imagine looking great & feeling comfortable while going BRALESS? That is what it's like wearing this bra! Musta been designed by a woman. I CHERISH my Sassybax!

Comfortable for everyday wear.
Written by A Happy Customer on 28th Jul 2014

I previously bought medium which is too small this time I bought a large which is a tad too big but would rather have it too big. Love this bra just wish it wasn't so expensive.

I Love This Bra....
Written by Beverly McMaster on 29th Jun 2014

Hello, I've worn Sassybax since they first came on the market, I Was Totally Sold on them, I Hate Back Fat!! I'm not what you call really over weight, but I'm one of those girls, I'm sure , like you, that can't Stand The Rumples In The Back, when you look at the back of a Tee, or anything!!! These Bra's have Made Me So Happy For So Many Years!! I buy several at a time, for fear they just might go out of business!! I LOVE YOU SASSYBAX!!!! ANSWER: Well thank you for your glowing review! Wow. We are so happy you are happy and can assure you that we will continue to provide our bras as long as we have customers like you. We have many but it never hurts to spread the word! Thank You! Amanda

Written by A Fairly Pleased Customer on 6th Jun 2014

Gives frontal support and a smooth back. It seems as if there is less band width in this bra than in the previous ones I've purchased. Amanda's answer: If the bra is too minimizing, this customer should go up a size. And we did shorten the band underneath the bust by 1/4 inch because we felt it was more comfy. Comfort and quality are our mission.

Back smoother
Written by Cindy Riley on 6th May 2014

This bra provides pretty good support. It is very comfortable. As promised, it really gives the back a smoother look! I've tried other "back smoother" bras, and was never impressed. This is a great product!

Written by Jane on 8th Apr 2014

I have been wearing Sassybax Bralettes, with underwires for years, I Love them. There is No Bra Line in the back, you get a fair amount of support... They are my Bra of choice everyday!!! I worry that they will stop making them so I always have new ones in my drawer!! I just Love Them.. I never put them in the dryer, they last forever... Amanda's Answer: We won't stop making them! Don't worry. We are the original no back fat bra and the one with the quality customers deserve.

Written by A Happy Customer on 28th Oct 2013

I've worn Sassybax Underwire Bras for many years now, they are so comfortable, and with the underwire you have the support you need, if you wear a C cup or more...I wear them kind of to minimize and support, I LOVE THEM!!!

The underwire & bra
Written by Pattiybt on 3rd Oct 2013

I love the fact that there are no back hooks so you get a nice clean line the fabric is nice and snug which hugs the body. I haven't bought any other brand of bra but Sassybax in 5 years. The Bralette wireless bra feels so nice when you want more support with no underwires. I recommend Sassybax to all of my friends!

incredibly comfortable
Written by cheryl gibbs on 10th Jul 2013

this bra offers support ( I wear a 38DDD) think it minimizes as well, and is very comfortable against the skin...the back coverage is great and gives a clean smooth look..it is snug to the body but does squeeze me, I will be ordering another one in the nude color....

Good option for different look
Written by Janice Jeffries on 26th Jun 2013

I have worn the non-wired version now for 8 years of the Sassybax bra and I decided since my bust was changing to try the wired one too. I like it for when I am wearing a really tight top b/c it gives me more separation between the breasts and a nice shape. The non-wire is perfect when I am wearing a buttoned shirt b/c it actually gives me a bit of minimizing and my buttons don't pull apart. So I guess I need both and will buy more of the wired on now. Great option.

Best bra ever!
Written by jmarie on 22nd Apr 2013

That I am so pleased with this bra is an understatement. It fits fabulously, feels great, and hides all unnecessary skin (well, let's call it what it is - rolls!) Thank you for the best bra I have ever worn.
