Size up!!! Ordered a medium my normal size and the support band is definitely too tight no stretching will give any room. In target swim I’m generally a medium bottoms with room, I would not think I would need a large in these but they’re made small and not mom pooch friendly. The quality of the suit is great, however, I purchased during a sale so no exchanges permitted. For reference: I am petite, narrow shoulders, 4 11 & 126lbs, small mom lower belly/32C cup, usually wear a small/med top and 4-6 jeans or small pants. Overall great fabric, quality, and fast shipping but not true to size so size up!
