Watch out Taylor Momsen. It ain't just you who can rock a red lip. Check out Sienna Miller last night at The Mysteries of Pittsburgh screening in New York. The actress had matched her lipstick to her red Marios Schwab cocktail dress - using beauty as her only accessory for the evening. Her golden glowing tan (probably more LA living than the faux kind, unfortunately) updated her otherwise classic red lip and chunky spider lashes. And take note of the tomato shade - it's much more youthful on her than a full-on shade. Simple yet effective. Sienna, you're our new beauty crush!
