Marcia Boxy Track Jacket

Black silky feeling, but not shiny, fabric with white hashtag motifs. Black with white stripes rib knit collar, cuffs, and waistband. Two side pockets. There is no size or fabric content tag. I'm pretty sure it's polyester, and I'm going to call it a size L. In very good condition. No holes or stains. There is a little bit of pilling on the rib knit trim, as pictured. Size L? Chest side to side 25" Waistband side to side 20" Back of neck to lower edge 23" Sleeve length 26" (from natural shoulder, not from dropped shoulder seam)
