The XXS–XS bodysuit covers US 0 to 2: bust 30 to 33.5 inches (76 to 85 cm), waist 23 to 26 inches (58 to 66 cm). It smooths the midsection and waist at medium-firm, holds the waist panel up with fully adjustable straps so it does not roll, and gives the bust its own shape through a built-in bra with no compression on it. The thong cut leaves no line across the seat; the mid-thigh covers the upper thigh under a fitted skirt or dress. Both open at the hook-and-eye crotch closure without taking the bodysuit off.
78% nylon and 22% spandex, bonded seamless edges that lie flat under fitted clothes, breathable mesh panels. Machine wash cold, hang dry. $29.99 on Amazon, shipped by Amazon with Prime and a free 30-day refund or replacement, designed and made in our own factory in Zhejiang, China.
Medium-firm means the bodysuit smooths the midsection and waist and is still comfortable to sit and eat in. It is not a maximum-compression garment, and at XXS–XS that matters more than in any other band, because there is less body for the fabric to work against. Measuring at the top of the range, bust 33.5 or waist 26, you will feel the firmest hold this band gives. Measuring at the bottom, bust 30 or waist 23, the hold is lighter and the fit is closer to a smooth second layer than a shaping one.
The bust is the exception. The built-in bra shapes without compressing, at every size, and you can wear your own bra underneath if you prefer. If what you want is maximum compression through the waist, this is the wrong garment at any size; choose a firmer one rather than a smaller band.
If your bust is under 30 inches or your waist under 23, you are below the chart. XXS–XS is the smallest band we make, and below its range the bodysuit may sit loose rather than smooth; medium-firm only works when the fabric has something to hold. Run the Fit Finder first: if the size it picks is wrong, we replace it free, on top of Amazon's 30-day returns.
