Buy the bra band size you wear, for example if you wear a bra size 12D, choose 10/12.
The band is firm to support the breasts, but also very stretchy and easily fits both ends in sizing, for example 10/12 easily fits both 10's and 12's.
I bought this not expecting it to be more than a sleep bra for me (I'm normally a 10DD-E but have had no luck with wireless tops for those sizes before) but omg I love this bra so much!! It's super comfortable and keeps me feeling supported enough to wear it during the day while running errands etc. I wish there was a padded version as well that I could wear to work, my nipples are a little too showy for this one to be suitable for work. I will definitely be buying more of these, currently waiting for some of the colours to be restocked 😉
These bras are so comfortable, lovely soft fabric and great to wear all day.
I'm usually a 16DD-18E, bought one 14-16 and one 16-18 and both fit perfectly, only real difference is slightly more cup coverage in the 16-18. Will absolutely be purchasing more
I'm a 14H so bought 16/18 DD-GG to give me a bit more room upfront. Fits great and far more support than I am used to from a wireless bra. Have basically switched to just wearing these
I love my bras I now have 3! They're so comfortable and don't roll up and seem to stretch but then return to being tight. I love the brand and what they're trying to do, highly recommend.
I wear these for work (outdoor, active) and after a couple of wears I'm quite satisfied. The straps are wide and firm, don't slip off and the band is snug to keep it in place. I wear a size 10/12 and the support is good.
