Meet the X Back, a back band hater's dream come true. With its innovative design (no back band here!), the X Back can be positioned low or high on your back, giving you the freedom to customize the fit. Perfect for open backs, racerbacks, and cutout designs... or just everyday comfort, if that's your thing.

Hand or machine wash in a wash bag to prevent snags. Nuudii loves earth-friendly detergents - that means no bleach! Hang to dry.

hate bras? us too!

For too long, we’ve been conditioned to believe that our boobs are flawed in their natural form. We’re calling BS! Say goodbye to subpar fit, hardware that digs, and the feeling of being pinched and squeezed by a torture device also known as a bra.

Say hello to boob freedom with Nuudii — the option between bra and braless.

FAQs

What size should I order?

Check out our size chart here! We’ve simplified sizing with our two-letter system: the first letter = your band size and the second letter = your cradle size—because boobs aren’t cup-shaped. For example, if you’re traditional bra size is 34C, your Nuudii size is MM.

What if my size isn't on the size chart?

Given the amazing diversity of our bodies, sizing remains somewhat of an inexact science. If you’re not seeing your size on our size chart we currently do not offer a Nuudii for your traditional bra size. We understand this is disappointing and can assure you that our team is working hard on new developments so we can continue to expand.

Do Nuudiis have padding, underwire, or hardware?

Nuudii is not a bra, it's the option between bra and braless. Our styles are free from padding, underwire, and hardware. Made from our 360-degree stretch fabric, our soft, formless cradles hug your natural shape, letting your boobs be boobs.

Savior for pregnancy and nursing

"I bought this bra while I was pregnant and my baby was causing my ribs to flare apart, making any traditional bra band excruciating. This bra was comfortable and gave me good support as my books changed size. Now on the other side, this bra is easy to lift on one side of the other for breastfeeding, AND i can pump wearing it too by putting the flange between the two shoulder stars on each side. It does fit snug, dont size down."

Emily C. (5/5)

The backless wonder

"This system is really comfortable. I love having no back band and I find it more supportive feeling throughout the day. On my body I’m not really able to adjust the cross to be lower on my back, so it’s always a little closer to a halter or t-back but it feels supportive, sexy and comfortable all day. It does sometimes require a readjustment in the cradle during the day, and it can start to ride up with moderate movement."

Liz L. (4/5)

great for cut out back tops

"I've never been able to wear a cut-out back because traditional bras were always in the way, and bras that would accommodate my chest either didn't work, or were too uncomfortable to wear. This takes some getting used to, but it really did an excellent job holding my breasts. I would definitely be able to wear a cut-out with this and not feel braless or uncomfortable. I wouldn't run in it, but it can handle a little dancing or a quick set of stairs without coming out of place."

Sara W. (4/5)

Wanted to love it!

"Cute but not functional for large boobs and small band - need bigger space for the ladies"

emma p. (3/5)

Worth the wait

"Love this style. It took forever to arrive."

lydia d. (5/5)

great, but not as good as the origional

"I love the color and it is really cute, but it shifts around, as you'd expect, more than the OG."

Nicole B. (5/5)

It was okay.

"I liked the idea of the X back system, it was alright. It gave me that light support which I appreciate especially when I don’t want to wear a traditional bra or nipple stickers. It was nice to wear it with tops that showed a little more back. I should have sized up, I felt like the cup size LL was smaller due to the X back design."

Claire W. (3/5)

Love the designs of the bra/Excellent Customer Service

"I wish the X back system bra and the additional bra I ordered came in bigger sizes (beyond XLXL). ! As a first time customer, I ordered 2 different bras in 2 different sizes hoping that they would fit me. I was very sad that they didn't. Customer service was very helpful in initially correcting my size on one of the bra before the incorrect size was shipped. And they were very helpful when I was returning them for a refund. Please continue designing these versatile bras and make larger sizes for those of us who really want them. I would recommend these bras for those who are fit, thin or athletic build."

Kimberly M. (5/5)

This is my holy grail

"I’ve been wearing this all day at my very active service industry job and it hasn’t budged. I’m a size G, and nothing has ever stayed in place the way this bra does. Obsessed."

Elise (5/5)

Most comfy bra ever

"Feels decadent wearing this. So comfy! Do not feel it there. I don’t even care if no nip coverage! Gonna buy another!"
