Boo! She may be subtle, but she's a mighty Boo! The Boo Sommers Sweatshirt has that perfectly lived in feel. This is a vintage-inspired crewneck pullover with raglan sleeves & banded hems. Made of Sherpa Fleece, 73% Cotton/ 27% Polyester. This is running a tad oversize. I typically wear Large in most tops, but I prefer the Medium in their Sommers Sweatshirts.
