Signature Tops are known for their creative fabric pairings—they vary in fiber content, drape, weight—read each listing for notes on fit and feel.
When there is a special fabric of limited yardage—as many of our signature tops have—making to order allows for all sizes to remain "in stock", so to speak, for as long as possible. It also prevents wasteful making of things people don't want. Sooner or later, though, we cut through the last of the fabric to make some for our boutique, and that's when sizes will disappear. Yours may be made to order, allow 1-2 weeks to sew it for you before shipping. Thanks for choosing to wear National Picnic.
