If you haven't already call up a pair of olive cargos for active duty and send those blue jeans back to the reserves. Cargo pants like Victoria Beckham's are as comfy and easy to wear as denim, working equally well day or night. The current model is tapered and hits above the ankle for a flattering, slim fit. Dress them up with a black tuxedo blazer and platform pumps, and you've got yourself a stealth evening look.
