I’m still thankful to have the 2X available in the original style, but I continue to hope that the underwire will return in 2X someday. I know that Amanda has tried and will keep trying, but I just like to remind y’all that I’m still here and still hoping ! ❤️

1XL Underwire Bralette
Written by Patricia Moran on 5th Mar 2021

I keep hoping, when I log into the site, that the 1XL Underwire Bralette will come back... The one I have ...which is probably at least 10 yrs old... probably longer... is coming apart ... it's been LIVED in by me... my favorite, favorite bra ever. I had a mastectomy and this bra is beyond perfect. Being a large breasted woman, it provides that extra support that the regular bralette doesn't ... I have 3 of the regular, but can only wear with loose fitting tops... I haven't given up... Response from Amanda I am not giving up on the bra in that size. If the factory can make it they will. Sorry it's been so long.

Love Sassybax!
Written by Jann Freed on 3rd Apr 2020

The only product I have tried is the underwire tanks. While I love them and they are the only thing I wear, I did struggle with having the wires pop-out too soon. I reported this to customer service. The last few I purchased seem to be better and last longer. I threw away all of my bras! Freedom. I feel naked without these body shapers. I buy more whenever they are on sale! Reply From Sassybax: We are sorry to hear you had wire troubles. We did address that problem and it's fixed now. We also recommend hand washing and line drying our wired products.

Love the Original; Dying to Try the Underwire But...

... I can never find it available in my 1X size. It must sell out as soon as it is available. Really appreciate what you do. Would just love to try this (maybe live in it!). Thanks

Nothing Holds Like Sassybax
Written by Patricia on 5th Jun 2018

I've never had a better product. This is not my first purchase of Sassybax products. I've been enjoying them for years. All I've done is added to my collection. You might be surprised to learn that when I look in my lingerie drawer, I have no idea which is my newest purchase. My 10-12 yr old purchases are in exactly the same shape as they were when purchased them. That makes this product very inexpensive. Nothing holds like Sassybax.

Great solid and comfortable product.

I enjoy the comfortable smooth fit and how much comfort in wearing a wonderfully comfortable structure.

Just step in

Create a smooth line with the torso trim. I love the underwire style. It is comfortable and easy to wear.

Great product
Written by undefined on 23rd Oct 2017

I've been wearing the underwrite torso trim for years. I don't wear anything else. It's comfortable, and I look great in my clothes. It takes care of that little roll around the middle that comes with age. I'm 70.

I have worn Sassybax for years, since Oprah mentioned it on her show! Unfortunately, the plus size underwire is never in stock. Amanda's Response I am sorry for the delay in stocking that size. We had some factory issues and as always, have refused to produce overseas. We will have that size again I promise.

Written by GG on 18th Aug 2017

I've been wearing them daily for years and have been so grateful to have them available in PLUS sizes 1X and 2X. However, they never seem to be "in stock" in those sizes any longer - not for a very long time. I keep hoping that the fact that you still show them in the size listing means that you do intend to re-stock them; so, when I receive your promotional emails, I often log in and try to place an order for a 2X in each color. But, just like today, there are none available. Please bring them back, I need them !

Sassybax underwire Torso Trim

I have loved this Tank for years!

Love Torso Trim--wish Sassybax would start making the original with no underwires
Written by undefined on 27th Jan 2017

I've purchased these for years, but as time went on, the only version of the Torso Trim I could find was the one with underwires. I hate underwires. So, I order the underwire version, cut a small opening at the side of the wire and pull them out. Still not as comfortable as the original version, but it works without making me crazy uncomfortable all day. RESPONSE from Amanda We make it without the underwire and have for 12 years! It's one of our Best Sellers! We added the underwire version later.

In love!

I have been wearing th-ese Sassybax products for going on 10 years! I had a breast reduction done and after graduating from sports bras following surgery I did not want to wear uncomfortable bras again! I started wearing Sassybax Underwrite and non-Underwrite Torso Trim. I have started friends liking them too! They don't ride up or down like regular bras do.. I have saved money that I would have spent on regular bras that wear out much to fast.

Absolutely Love...

This is a beautiful piece to add to your shapewear wardrobe. Slimming, sexy, comfy and very well made. Nice attention to detail. Thanks Amanda for a beautiful product line.

i will never wear another!
Written by undefined on 6th Jun 2016

The Underwire Torso Trim is the only bra i have worn since i first learned of the brand, SassyBax. With it, i feel "pulled together" and as though i were fairly young and my body attractive once more! Many Thanks!

Best product ever
Written by undefined on 6th Jun 2016

I've worn the underwire torso trim for about 15 years. It's the best product on the market. I wouldn't go back to a traditional bra. This is so comfy.

White strings?
Written by Curious and Happy on 5th Apr 2016

Love Sasybax and have had more than a dozen of these so I am wondering why there are white strings tacked to bra in four places....apparently where underwire is attached? None prior ever had this issue. Wearing it anyway and hope it will hold up as well as others I've purchased. Amanda's Response This is called tacking and it reinforces the wire.

Best undergarment ever!
Written by Happy Customer on 29th Feb 2016

I have been wearing this since I had a breast reduction done almost ten years ago. After having the surgery and needing to wear sport bras for a considerable amount of time, I did not feel I wanted to go back to bras that didn't stay where they were supposed to. I can't leave out muffin top and sometimes muffin bottom. This Sassybax takes care of those issues and is still more comfortable that any bra I ever wore. I no longer wear any bras!!! Amanda's Response: Happy we could make you happy.

I can't go back to a regular bra
Written by Kathleen Bradley on 9th Feb 2016

I give this bra five star as it make me feel like a star. The bra shapes you and holds you in beautifully. It's great for my back and for shaping me. I can not go back to a regular bra. I only wear the Underwire Torso Trim Long Line Bras. I have recommended them to some friends who are now thanking me..

Nothing better
Written by Happy No More Bulge Customer on 26th Oct 2015

I bought one years ago and they last forever and very comfortable. Love that they are high up under the arm and it reduces that underarm bulge

Comfort and support, love this bra
Written by Jeanne on 9th Oct 2015

I love the support this product gives not only in the breast area but all over. There is only one complaint I have and that is with the underwire. The wire should either be tacked into place or should be larger to fit the full casing. I have large breasts and with the underwire shifting inside the casing it will pinch occasionally until i reshift it. There is about 1/4 of the casing that is empty and that is a lot of space. A longer wire might eliminate that problem. But overall I really do love this product. Amanda's Response: Thanks for the feedback! We tried a longer wire and it kept pushing out of the casing. You could tack it if you want to try that.

I am a fan!
Written by Patti Ferreira on 12th May 2015

I am a fan of Sassybax products! I wish that the shoulder straps were a bit wider as that would add to the comfort of larger busted women! I buy the wired torso trim, but I remove the wires to make that bra more comfortable for me! It has more support for me that way than the regular torso trim and is very comfortable! Amanda's Response: What a great idea Patti. Removing the wire still leaves the casing under the cup which in itself provides shaping and support. Clever girl! In regard to the straps, moving them any further apart would be great for some women with larger breasts but we base our products on the average. Each size does however go up in distance between straps.

Written by A Happy Customer on 2nd Feb 2015

I bought this longline Sassybax years ago and had "outgrown" the size I had. So. I wanted another one and have found the large fits me. But what's more important, this is the only longline UNDERWIRE bra that helps with smoothing my back and giving me the bust-lift that I need! I feel most large- busted women need underwire lingerie. Spanx does not have longline underwire! Could be a continuing sales point! Thank you! Company Response: We are happy you are pleased. Thank you for your review!

I love this product
Written by Elizabeth on 24th Oct 2014

I even cut the under wires out of it and still get great support. It is very comfortable and I wear mine year round. Smooths out my lumps, a great value

Holds tight!
Written by Sally on 15th Dec 2013

The first time I put this on I thought I'd never get it over me head. It was so tight. The second time it was easier. I do like it, don't know if it changes my shape any - but then maybe it can't work miracles! I was worried about the underwire but it's comfortable and works as kind of a push-up bra. I'll keep wearing it. Customer Service REPLY Our shapers should never fell tight. They should feel snug and comfy. You might try the next size the next time you purchase......My other suggestion is that you step the bra like a bathing suit. It saves stress, hair and makeup! And while nothing will actually change your shape but a corset, when we are smooth and line free we look not only more finished but thinner. Amanda Kennedy founder, designer

Most comfortable product I've found...
Written by A Happy Customer on 13th Dec 2013

I've been buying the Underwire torso trim for several years now. I love the comfort they give, and the support. I much prefer this to a bra. Much more comfortable.

Can't live without it
Written by A Happy Customer on 12th Dec 2013

This is a must have product. I will soon have 7 pair. Giirls, don't go without wearing the torso trim!

I love this sassybax!!
Written by Pam on 20th Nov 2013

I have bought these bras for 3 years.. I love them because they cover my back bulge.. So comfortable. Just wash them by hand.. I have been lazy and washed them even in a mesh bag. Just be mindful and take care of them properly ..

Written by undefined on 24th May 2013

Have been wearing underwire torso trim for several years. Cannot imagine going back to any kind of traditional bra. This is ALL I wear for breast support & coverage.
