Adorable Lulu Lemon windbreaker

I love this jacket with feminine rushing details and smocked shoulders. I can’t locate the size sticker they typically screen print inside a pocket but I’m certain it’s a medium. I now wear large so this is just too tight on my bust. (41”) When I was a 36, it was perfect. It’s in great shape but part of the main zipper pull broke off in the washer YESTERDAY. Grrrr. Anyway, last pic shows the broken one and the non broken one for comparison. Still works perfectly, just a partial pull. Sad to see it go.
