- Rated 5 out of 5 stars7 hours agoAbsolutely Love These!
I ordered a few of these tanks on a whim about a month postpartum. I absolutely love them. Pre-pregnancy I was a 32G, and honestly have no idea what size I am now but I’ve had a REALLY hard time finding a maternity bra that fits comfortably now that the girls are bigger. I love that this tank is compressive but the fabric is thick so it sucks me in and makes me feel more secure in my new body. I find it supportive enough to forgo a bra altogether. The length is also great so they don’t roll up like more cropped tanks tend to do. I bought 4 and wish they came in more colours and I would stock up for sure!

Love this tank. Sized up one size for comfort and it is still plenty snug and supportive. I have now bought it in all 3 colours.
Sheila R.Verified BuyerWas this helpful? - Rated 5 out of 5 stars2 weeks agoI'm in love.
I was already a fan of the v-neck luxe-lift tank but they've been relegated to firmer support outfit days.
The SculptRib tanks and tees are constant wear now and I'm a heavy chested lady. I would love to see the tank and tee evolve into SculptRib mini, midi and maxi dresses.
AnonymousVerified BuyerWas this helpful? - Rated 5 out of 5 stars2 weeks agoThe best tank!!!!
I love this tank, it's SUPER fitted and flattering as it sucks you in, material is on the medium to thick side but doesn't look bulky and as it's cotton it's not too hot for summer. I am a size 10 / 159lbs and the L fit me well. It's designed to be tight, and the medium would have been too small. Please bring this out in some more colours Knix! Some brights would be fun, as well as some darker shades for fall.

It is comfortable but I would never wear it on its own, only to be layered under another shirt. Nipples are way too prominent for my comfort level.
Colour is quite nice.
Janin R.Verified BuyerWas this helpful? - Rated 1 out of 5 stars4 weeks agoSculptRib Tank
Difficult to get on & off. Too constrictive. Washing didn t make much difference or sticking it out trying to see if it became more comfortable
Please help me return these 2 items, different colours but both too uncomfortable

Ordered same size as bras. Found too constrictive & uncomfortable. Didn t find washing made much difference. Trying to return, waiting for responsr. Not sure if sizing up would help????!
