Done in delicate silk with French lace trim throughout, this square-neck slip dress is even more beautiful on the body than it is on the hanger. Pintucks at the bodice tailor the waist ever so slightly while the skirt falls straight to just below the knee. There’s a side slit that extends up to midthigh, and a concealed zipper in back for easy on and off. Suspended by pin-thin straps, it’s effortlessly sexy—great for a first date, or a standing date.
