Measure Your Under Bust
Measure Your Full Bust
Wearing an unpadded bra, wrap a measuring tape around the top of your ribcage. You’re looking for a snug fit - so we recommend tightening on the exhale and noting the smallest measurement to the decimal.
Wrap the measuring tape around the fullest part of your chest, making sure the measuring tape is paralell to the floor. Relax your shoulders and measure where it falls.

- Rated 4 out of 5 stars14 hours agoShape and smooth bra
I went into the store to try on. I don’t think they were the most experienced salespeople so it took a bit to find the best fit. I think the value is decent, I’d like to see it retail for maybe a little less for what it is. Would buy again maybe when on sale.
JCJennifer C.Verified BuyerReviewingShape & Smooth Bra - Rated 5 out of 5 starsYesterdayPerfect Bra
The first bra in a long time that t straps dont fall down. I love this bra. I bought one in beige and black.
SRSherry R.Verified BuyerReviewingShape & Smooth Bra - Rated 5 out of 5 starsYesterdayLove this style of Bra
Please DON'T stop making this style. For me it's the best fitting of all your bras. Thank you for making a style that doesn't have those ridiculous removeable pads which never go back once their washed and I realize you don't wash them with the pads in. They just never go back properly IMHO. Please bring it in more colours. I would also love it in a navy blue.
MMMary M.Verified BuyerReviewingShape & Smooth Bra - Rated 4 out of 5 starsYesterdayBra Whew Tight
I think I remember that bras are very snug until one wears them for awhile. That's what I am doing--but whew is it tight!
I do have some bulging in the armpit area, but I'm hoping that will correct itself too.
I do love the bra though.
MCMarilyn C.Verified BuyerReviewingShape & Smooth Bra - Rated 5 out of 5 stars2 days agoShape and smooth bra
The most comfortable bra I’ve ever owned, I only wish I’d bought it sooner! I highly recommend these bras!
ADAngela D.Verified BuyerReviewingShape & Smooth Bra - Rated 5 out of 5 stars2 days agoShape and Smooth
I ordered the XL but I couldn’t hook it up. I exchanged it for a XXLand it fits perfectly. Hey are so soft and smooth. I purchased the pink and beige bras.
SLSuzie L.Verified BuyerReviewingShape & Smooth Bra - Rated 3 out of 5 stars2 days agoThe bra is okay
I prefer the wider clasp and this one didn’t have it.
