MICHELLE DOCKERY

Michelle has plenty of experience with corsets, but the lace peeking out at the sexy neckline of her LBD isn't exactly something we can see Lady Mary wearing. Neverthelss, the actress dons the all-black look to the Downton Abbey Childline Ball in London.

ALEXIS BLEDEL

The actress looks so pretty in her blush BCBG Max Azria dress (featuring a cutout at the neckline and black waistband ) we think she should consider the hue for her wedding gown. She adds a touch of edge with studded pumps at the Us and Them screening in N.Y.C.

REESE WITHERSPOON

The silhouette of Reese's strapless dress (worn to the Elle Women in Hollywood event in Beverly Hills) may be incredibly simple.
