Miu Miu lambskin biker bag, $1,970, at select Miu Miu stores, miumiu.com.

I’m totally revved up over Miu Miu’s tough-girl Biker Bag, which hits stores in November. It comes in classic black and an assortment of fun colors, but I particularly like this chocolate brown, black, and white version with gold hardware and exposed zippers.
