From the J. Crew Website Description

We created this timeless ball gown with fine silk dupioni, a fabric known for its unique lustre and subtle texture The lack of embellishment on this silhouette lets you pile on the jewels or just revel in its stunning simplicity—it's your day, so it's up to you. Another reason to love it? It's finished with discreet on-seam pockets for stashing extras like lipstick and tissues.

Silk. On-seam pockets. Back zip with button closure. Lined in silk habotai. Ball gown silhouette. Fitted bodice with interior boning for added support.

I am 5'4" and wore 3 inch heels with this dress. I had the length altered accordingly and had one layer of crinoline in the petticoat removed but nothing else needed to be done to the dress. I still have everything that came with the dress including the box, the hanger and the dress bag.
