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

Last updated 2 months ago
Customers say this sculpt rib t-shirt provides supportive compression that allows many to go braless while remaining comfortable all day. The fitted design hugs the body and smooths the silhouette, though many recommend sizing up as it runs very tight. Users appreciate the soft, quality cotton material and find it excellent for layering under sweaters or cardigans. Common feedback includes concerns about the white version being see-through, with nipples showing through the light fabric. Some mention the shirt rides up or feels restrictive in the shoulders and armholes. While larger-busted customers find it offers good support for casual wear, others note it may not provide enough structure for all body types. Many have become repeat purchasers, praising its versatility for travel, lounging, and everyday activities.

This is just a perfect t-shirt. I love to be able to not wear a bra without people noticing I am not wearing one. This is perfect. I will buy them in every color. I am not wearing any different t-shirt ever anymore

I love the sculpt knit line. I have a large bust (36E) and I don’t feel comfortable going out without a bra, so I use the tshirts and tanks as layering pieces when I want a bit of smoothing, or on their own when I’m at home and want light support.

Love this tshirt. They fit nice and snug and suck everything in nicely with no sausage in casing situation. The white is a little see thru so although I could go braless I wouldn’t with the white. I’m typically a small to medium in tshirts and I got mediums.
