Get the support of an underwire cup with our new Rosanna wireless bra with built in stabilizers and molded technology to keep everything in place. Our Rosanna Cup is named after our cousin who was diagnosed and battled breast cancer. She's a fighter, much like many other women out there, so we decided to make something special, a bra that's wire-free, supportive enough to hold everything in place and comfy for all day wear with shaping and support that can also look chic and special with our interchangeable straps.

The Construction

It is a dual side clasping molded cup with light foam padding and an ultra soft outer body fabric. Stabilizer material around the under bust as well as underwire channeling material for extra support giving you the same benefits as an underwire bra. Sizes 0 - 3 (AAA - B in our old sizing) have a push up pad at the bottom/side of the cup for a gentle lift. Interchange our back bands and shoulder straps with this cup frame.

The Deets

It is a comfortable all-day base, your go-to bra for everyday wear. It can be worn with a back strap + shoulder strap for a complete bra look or with a 2-in-1 racerback. It cannot be worn as a strapless.

How It Works

  2. Choose a back band. Shop Back Bands

    The Rosanna cup comes with a pair of matching 1" black shoulder straps included. A back band must be purchased to wear this bra.

Great concept!! Size up though.

The bras are great! The concept is so simple I can’t believe no one thought of it before this. They are definitely a company you want to go a size up on though.

I was hesitant to try

I was hesitant to try this set, but I absolutely love it! I am ordering a plain beige back and straps right now because it's comfortable enough to wear as an every day bra. I am so happy with the variety of this set, it's really fun. If you are on the fence about ordering, do it! I also ordered according to the recommended size conversion and it fits perfectly.

I have to say thank

I have to say thank you. I'm literally in tears. I was so skeptical since I've had a big chest my entire life and there have been so many products that were put on the market that never fit right or worked when it came to strapless or at least something cute I can wear that would show. I stopped caring if you could see my straps years ago. When I stumbled on your website I did my homework, I read reviews, I watched videos and still was skeptical. My thought process though was go big or go home, so I took a chance, made my purchase and I am so ridiculously grateful that I did. I've missed out on events like weddings and new years after renting dresses or finding only dresses that would show my hideous bra. The anxiety of not having anything to wear or being uncomfortable because you can tell it's my bra and it's an ugly boring normal bra since no one makes anything cute for 32DDD boobs was something I've always hated dealing with. Especially if I tried one of the other options and of course my boobs felt like they were flopping everywhere. Uncomfortable, embarrassing and just stopped going to events because of it. Not anymore thanks to you all. Thank you again, so much for creating a product that is just amazing, price friendly and actually supports my boobs the way I want them to be with super cute backs I can't wait to show off. You guys have literally changed my life. I can't wait to see what other amazing backs you guys come out with, thank you thank you thank you.
