Sister Sizing Explained

Do you know that most women do not know their bra size? Or even how bra sizing truly works?

The letter of your size is not what you think at all!  The letter is only meaningful relative to the band size and the volume of your cup goes up or down depending on that band size. 

You're not going to believe this but a 32D is the same as 34C & 36B!

So when converting your traditional bra size to ours, keep in mind your letter might be different than the one you're used to!

But trust us, it'll fit. So check out our easy size converter and get the perfect fit.

I love these bras! I’m too endowed to go without a bra, so these allow me to wear the backless or cut out shirts that are really popular, while still getting support.

OMG I LOVE this bra and how customizable it is. Instead of needing to get a bunch of different bras in different colors you can just get different straps and backs!

Sabrina

Customer for life! I just got mine in the mail and oh my gosh!! I'm in love! Time to buy a ton of backless shirts that I've never been able to wear before. The fit is amazing.

Amber

I'm so happy with my set! It's a struggle finding bras that have big cups and small bands and I LOVE the idea!
