In a Virtual Fitting, one of our Knixperts will connect with you via video chat to help you find the perfect fit in any of our items—bras included.
They’ll double check your measurements to figure out your size, show you styles that could work for you, and answer any of your questions. They’ll also assist with exchanges/returns.
P.S. Keep your camera on or off. Our Knixperts are good either way!
- Sarah M.Verified Buyer1 month 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.

I had given up finding a wired bra that was comfortable, but this bra feels so comfortable I can wear it all day and not want to hurry home and take it off.
