I size down one side in the jeans for a more snug fit because they run lose and will get looser as you wear them the first time! They also run SHORT. I prefer a long in this specific style being that I’m 5’7. Sweatshirt is my true size small. Sized up to a 9 in slippers! I’m an 8-8.5. LTKGiftGuide LTKootd LTKHoliday
