The Room You Walk Away From | Polka Dot Keyhole Back Halter Top

Polka dots on a halter-neck blouse with a keyhole opening at the back, fastened with a button and knot so the back becomes the feature rather than the front.

A back detail is the most underrated design choice there is — you never see it, and everybody behind you does all evening.

Dress for the room you are walking away from.
