John Varvatos. Silk.Usually a menswear designer but he has done women's clothes.

I bought this hot number in the Vegas John Varvatos store. It's Silk knit. Wore it for a few hours to a cocktail party once. It's perfect. It's sexy but in a happy elegant color dusty blue-- my fave! Elastic lays smoothly across bust. I have 34D bust, and it would fit smaller but bigger may be too tight. Beautiful fit with the way the seams are designed and sewn. Total length 30" from top of bust to bottom. Ask questions.
