Purchasing my first Define jacket from lulu, and have been struggling between the Clubhouse Blue and Black. Any recommendations on which color? I’ve also tried a size 4 and 6 and couldn’t decide. Size 4 feels more snug but not too tight, size 6 feels more relaxed but a little lose on the arm and back. I’m usually wearing their sport bra in size 6 though. Girlssss help me!
