Sized up to a medium in the blue sweater from TJMaxx, couldn’t find it online, linked similars! Size XS-small in the ribbed lounge pants, the are meant to be a little oversized, so if between sizes size down Leggings are not the best, but make a great base layer, they run a little big! Boots fit tts, I’m a 6-6.5 and got a 6.5! LTKstyletip LTKfindsunder50 LTKHoliday
