NWT J. Crew Collection Chocolate Cosmos Dress, sz 14. This is gorgeous and in absolutely flawless condition - it's just hung in a dust bag in my closet it since I bought it. I do think it fits true to size - if you wear a size 14 in J. Crew fitted dresses, especially the suiting ones, this will work for you.
From the J. Crew website:
Our design team found this motif in an English print house and recolored it slightly for a sophisticated (and season-spanning) take on florals. It's tailored in a feminine fit-and-flare silhouette from silk gazar, a luxe fabric that's lightweight yet also slightly structured.
Size & Fit (from the website):
Fitted at waist. Falls below knee, 38 3/4" from high point of shoulder (based off size 6).
Retailed for $398 (it truly is a special 100% silk Collection piece), which is what I paid.
