The hardest thing to find is a layer that adds warmth without adding bulk!

Just imagine slipping something soft over a favorite white shirt and watching the whole outfit come together — sleeves still free, coat still comfortable, shoulders no longer cold. Now stop imagining, because the Nancy was made for that job. A V-neck knit vest with two patch pockets, a button front and a tiny embroidered flower on the pocket, in six colors that live comfortably alongside everything you own.

• The Perfect Mid-Layer
  No sleeves means no bunching under a jacket and no fighting with cuffs. It adds a full layer of warmth across the chest and back and disappears under a coat.
• A V-Neck That Lengthens
  The V opens the neckline and draws a long vertical line through the body, which is far more flattering than a straight crew on most shapes.
• Pockets With A Purpose
  The two patch pockets sit at exactly the right height for your hands, your phone or your glasses, and they give the front a relaxed, lived-in balance.
• Six Colors, All Neutral-Friendly
  Cream, rust, camel, chocolate, olive and black — a palette that works over white, blue and denim without a moment's thought.
• Fit Note
  Relaxed through the body, true to size, S through 3XL. It is cut to go over a shirt, so take your usual size and the room will be there.

If the word vest brings to mind something shapeless, this will change your mind — the V-neck and the softly skimming body do the opposite. Layer it once over a crisp shirt and it will become the fastest way you own to look properly dressed.
