“This runs very small--at least the particular top I ordered. I usually wear an XS in this brand, and well, it would've fit 12-year-old me who was 5'4" and 95 lbs. At 5'7" and 130 lbs., a medium likely would've been my size. Unfortunately, the joggers didn't fit me either (too tight around the space between my ankles and calves), so I just returned both.”
