There is always one event a year that asks for more than a good blouse — and nothing in the closet answers it!

Just imagine a long, weightless dress in deep rose that moves half a second after you do. Now stop imagining, because this is it: fine layered chiffon, a deep wrap front knotted at the waist, long sheer sleeves and a high slit that makes walking effortless. It is the dress for the wedding, the anniversary dinner, the photograph that stays on the mantelpiece.

• It Moves
  Layers of fine chiffon catch the smallest bit of air. Standing still it is elegant; walking, it is genuinely beautiful — and that is what the camera picks up.
• A Waist You Tie
  The wrap front knots at the middle, so you set the tightness yourself. Loosen it after dinner and no one will ever know you did.
• Sleeves, Not Straps
  Long sleeves in the same fine fabric cover the arm without adding any warmth at all. You can wear this in a hot room and still feel covered.
• Deep Rose Throughout
  One rich, saturated color from shoulder to hem. Against silver or gold it reads as expensive, and it photographs far better than black does in evening light.
• True To Size
  Cut true to size in S through XL. The wrap front adjusts a full size in either direction, so if you are between two, take the smaller and tie it where it suits you.

That one event a year deserves a real answer. This is it — and it will come out of its garment bag for every occasion after that one too.
