Beautiful JSK from Baby, the Stars Shine Bright featuring Swan Lake ballet print. I believe this is the Navy colorway.

It has a corset style design with boning. Would best fit a US XS or S. (Fits me nicely as an XS.)

I love this dress and keep meaning to wear it, but have realized it's not my personal style.

The condition is great, although I would say there is a very slight feeling of wear as expected of an older garment (i.e., it does not feel brand new, but has no flaws I can perceive).
