Katy Perry put a new spin on the "bag lady" phrase by wearing a Balenciaga dress that looked more like a piece of luggage than apparel.

Irony plays a large role in Demna’s Balenciaga offerings. The designer has created everything from platform Crocs to high-fashion Erewhon merch, and to understand his clothes, one must have a sense of humor (even if the jokes are questionable).

Katy Perry stunned Paris Fashion Week in a dress made entirely of fanny packs, turning dadcore into high fashion.

Far from your average LBD, Katy's dress appeared to be made entirely out of bum bags. As in, the pouch bag originally associated with middle-aged dads who wore the accessory clipped around their waists on a day out at a theme park.
