Surenow Womens 2 Piece Long Sleeve Crewneck Pullover Top and Drawstring Joggers

Pre-owned sweatsuit set. It's sort of a t-shirt material. I liked it because I do have many matching sweatsuits but this one was lighter, almost like a t-shirt material throughout. It's super comfy and great for relaxing or working out. However, the problem I have with it is that the white stripes on the arms are not flexible or stretchy at all and are tight on my forearms. I noticed this was a problem in the comments on the Amazon post but I bought it anyways and now can't return. This is size small. Note: I'm 5'0" and about 110 pounds and both the sleeves and legs are long on me. Probably would fit someone a few inches taller perfectly.
