Sienna Miller jazzed up a pretty ordinary outfit with the Katherine Kwei Joyce Carry-All in black over the weekend. This bag is a great take on the fringe trend, with leather strips revealing a peek of metallic underneath and tying up neatly in knots at the bottom of the bag. The calf and lambskin bag, $625, is available at Luna Boston.

This is such a realistically doable look – just pair the bag with jeans and a pea coat and you’re channeling Sienna with considerably more ease than some of her red-carpet looks would require.
