Suno Jacket

The Look: Contrasting Sleeves
Want to see a great trick? Just slip on a jacket with contrasting sleeves. It draws the eye to your middle and carves out a curvy hourglass. This particular piece works wonders with winter white—but also rocks jeans.

Rachel Roy Jacket

The Look: No Sleeves!
The sleeveless jacket gives serious hip and tush coverage, updates a dress, and pulls a blouse and pants together just like that. I like using dark green as a neutral, nipping in the waist with a belt, and pairing it with a sexy pencil skirt.
