Who Wore It Better? Calvin Klein Satin Romper Ah to be an Olsen twin . . . the money, the fame, and being able to root around in your sister's cavernous closet. Mary-Kate did just that at the premiere of 21 with this black Calvin Klein satin romper that Ash wore back in 2005. Mary-Kate, of course, put her own twist on it with a bold hot pink belt and her oversized (well, could just look that way on her) Miu Miu tie dye clutch.
