Mike Kelley Tote Bag

Mike Kelley tote bag, $40, openingceremony.com.

I'm not exactly sure when the cotton tote became the new souvenir T-shirt, but by now I have hundreds of them — from fashion shows, store openings, book launches, you name it — and I use them for everything. The latest addition to my collection is definitely going to be this wonderful pink monstrosity, a collaboration between the kids at Opening Ceremony and the Mike Kelley Foundation for the Arts to celebrate the opening of a retrospective of the late artist's work at MoCA in Los Angeles.
