We love Jessica Alba‘s casual style — fun T-shirts, cool cardigans and great jeans. So we had to look twice at her outfit for a friend’s party today in Los Angeles. Her accessories, including her luxe Gerard Darel snakeskin bag and lace-up sandals, are totally killer, and Blair Waldorf herself would covet that feminine ruffled blouse. But we just can’t decide how we feel about Jessica’s high-waisted purple pants, which are pleated and pegged at the ankle. When you are gorgeous and fit as Jessica, you can pull off a look this tricky, but for the rest of us, this might be one look we have to sit out. Tell us: Would you wear Jessica’s purple pants?
