Size and Fit Guide
How to Measure
In order to select the correct sizing, we recommend you take the following measurements using a soft tape measure. If necessary, ask someone else to help.
Bust
Wear a well-fitting bra and measure around the fullest part of your chest, keeping the tape level and snug but not tight. The number where the tape meets is your bust measurement.
Waist
Measure around the narrowest part of your torso, usually just above your belly button. Keep the tape snug and level, but not tight. The number where it meets is your waist measurement.

Reviews Summary
Generated by AI from 100 most recent customer reviews
Last updated 2 hours ago
Customers say this tank is comfortable and provides good support for going braless, though many note it runs significantly small and recommend sizing up one to two sizes. The fabric offers gentle compression and a smoothing effect that holds everything in place. Many reviews mention the tank works well as a layering piece under sweaters or shirts. Common feedback includes concerns about the white version being see-through, with some noting nipples are visible through the fabric. Users appreciate the cotton material and find it breathable, though some mention it feels less soft than expected initially. Several customers report the armholes can be tight or uncomfortable. The tank tends to ride up for some wearers, and many wish it came in more colors.

One of my fav tanks!
Jen H.Verified BuyerReviewingSculptRib™ Cotton Tank - Rated 5 out of 5 stars2 days agoGreat feel and fit. Holds its shape.
Love it. Plan to order in more colors. I like wearing it over my bra. Somehow the bra seems to feel better.

This is great! Fit very snug but holds you in and feels wonderful! I would recommend it to anyone. I can't wear it without a bra but under things it is great!
Sherry M.Verified BuyerReviewingSculptRib™ Cotton Tank - Rated 5 out of 5 stars2 weeks agoMakes your boobs look amazing
I am a 34G and this tank makes my boobs looks amazing. I bend over and adjust my breasts into place like I would a bra and the tank holds them up and in place and cinches the rest of my body. Plus it’s almost entirely cotton. Your nipples will show through the fabric so wear pasties if that bothers you.
HillVerified BuyerReviewingSculptRib™ Cotton Tank - Rated 5 out of 5 stars3 weeks agoPerfectly fitting
SculptRib cotton tank is my new BFF. I want one in every color! For me, no bra is needed and it’s the perfect base layer or great by itself. Accentuates my curves and holds me in all the right places. Love love love!
Holly M.Verified BuyerReviewingSculptRib™ Cotton Tank - Rated 5 out of 5 stars3 weeks agoDoesn't disappoint
This is my fourth sculpt rib cotton tank. I absolutely love the quality fo these - they don't stretch out, and I can go braless if I'm running errands (which is impressive for my DDs). I always size up a full size (sometimes 2) as they are not stretchy and with my curves they can be too short otherwise. I am normally an XL-XXL, and I go up to a XXL for these tanks.

Excellent fit. Fits very well.
D S.Verified BuyerReviewingSculptRib™ Cotton Tank - Rated 5 out of 5 stars3 weeks agoWow, what a tank top
Surprised how much i love this tank. Soft with enough compression. I will be buying other colours.
Debi B.Verified BuyerReviewingSculptRib™ Cotton Tank - Rated 5 out of 5 stars3 weeks agoJust right bra replacement
I’ve got this tank in white, black, dark green, and light blue. Yes, you can see some skin color and outlines through the lighter colors, but that’s fine with me. I plan on wearing the lighter colors underneath cotton gauze and linen summer tops as a bra replacement. I’m so glad these tanks are made with mostly cotton! Nylon is just plain stifling in warm weather and it STINKS! I bought size medium according to the sizing chart and find the fit snug but not pinching. And even though the hem doesn’t quite stay put over my hips, the fabric doesn’t roll or bind.
