Aerie Gotta Jet High Waisted Pants and Polo Sweater in Toasty. The top is a medium and the bottoms are a small as the pants run pretty large and long. Both are also very stretchy. For reference, I’m a size 8/10 pant and medium shirt at American eagle (40” around the bust and 30” waist) and they fit perfectly. Waist 28”. Pit to pit 28”.
