5’4” 125 lbs athletic build – the size small was tight. The size medium just right. These actually cover your bum so they don’t ride up and become a wedgie. Very difficult to find hipster underwear now that actually have full coverage across the rear of the gusset. Fabric is nice and soft. They washed up well in hot water (line dried). BasicsByMail shipped my one pair by letter mail so shipping was reasonable and fast!
