Whether she’s rocking a crocheted Marc Jacobs gown, a midriff-baring Versus dress or bright blue Proenza Schouler for J Brand scribble jeans, the style star is never one to shy from taking fashion risks. And last night proved no exception when she arrived at the Harry Winston Court of Jewels event in N.Y.C. in a super-sheer Marchesa lace jumpsuit. Complete with see-through harem pant legs, a low-cut back and visible lace hot pants, Leighton’s look was anything but reserved.
