Postpartum Opinion
Fit Type: Boyshort, Size: X-Large, Color: Assorted Colors
Bought the boy shorts size XL for postpartum and am still wearing them 8 months later! Holds all the postpartum goods in but are super stretchy too. Sooooo comfy! They do roll up when putting pants on but if you’re wearing them to bed or around the house, amazing!

To fit or not to fit?
Fit Type: Boyshort, Size: XX-Large, Color: Assorted Colors
NIce quality, comfortable fabric, dries quick, and retains color after multiple washings. However; the fit did not work 100% for me. The legs kind of rode up and the boy shorts had a tendency to ride down, especially with consistent bending up and down activity. Good product but not a perfect fit for my shape. The bikini style was ideal and purchased multiple times.

Very comfortable, right length
Size: Large, Color: Black,grey
This product arrived as described. I like the trunk length, not the boxer brief length. They are comfortable. Hold up well when worn and washed. I don't seem to sweat as much. These were ordered to replace ones ordered about 2-3 years ago due loss of weight, had to down size. The waist band doesn't roll as like other brands.
