- Sarah M.Verified Buyer4 months agoRated 5 out of 5 starsBest bra yet
While I love Knix and all of their bras are comfortable, this might be my favorite and best fit. The lift is great and my bust looks awesome. No double boob, no gaping. The comfort is perhaps not quite as good as wireless but with a big bust, this is a game changer 36E.
