Layering is guesswork — and on a cool morning it usually ends with two things that almost go together!

Just imagine a satin slip dress and a fine V-neck sweater made as a pair, in exactly the same shade, cut to sit smoothly one over the other. Now stop imagining. Wear them together when the air is sharp, or take them apart and use each one on its own. The matching is already done.

• Cut To Layer
  The sweater is shaped to sit over the slip without bunching at the waist or pulling at the strap. That is the whole difference between a layered outfit and two garments worn at once.
• The Slip Falls Straight
  The satin skirt drops from the shoulder in one clean line and does not cling at the hip. It catches the light down the length of you, which is what makes it look expensive.
• No Cold Shoulders
  The sweater goes straight over whenever a restaurant runs cold. You keep the dress you chose and lose none of the warmth you need.
• Two Wardrobes In One
  The slip works alone for an evening; the sweater goes over your own jeans on an ordinary Tuesday. One purchase quietly covers several occasions.
• True To Size, S To 3XL
  Both pieces are cut true to size — take your usual. The slip is straight rather than fitted, so it does not need extra room through the hip.

The guessing is the tiring part. With these two there is none of it — which is why this set ends up doing more work in your week than anything else in the drawer.
