Your Transitional Helper: A Long Vest
Backless dresses are great because they’re demure from the front and surprisingly sexy from the back, like on the Azzaro runway and on Kate Mara. Since skin exposure in the fall (and winter) is generally a no go, keep your back under wraps with a lengthy vest. Treat it like an accessory: Experiment with colors, fabrics and styles. Try belting it or layering it under a jacket.
