this set is so teaaaaaaa i got a size M in both top and bottom. for reference im 150lbs and im around 5"5/5"6 with long ass legs and they go down to my ankle. i wish i sized up on the top, i have 38C chest and it's a little small r around there. the quality is so soft, and the colour is amazing. warm enough for -10C/14F but anything colder than that you'd have to layer. so cute for running errands or just staying in the house. can wear the pants with other tops and vice versa. so versatile when it comes to styling. worth the price, PLEASE BUY GUYS YOU WILL NOT BE DISAPPOINTED.
