Chicago (CBS) — Smashing Pumpkins frontman Billy Corgan popped up at a pop-up shop in Chicago this week.

Corgan and his partner Chloe Mendel brought her Masion Atia fashion line to PAWS Chicago in Lincoln Park. Sunday is the last day to buy one of Mendel’s stylish faux fur coats.

A portion of proceeds from sales goes to PAWS.
