Unreal. This was bought in LA and it feels every bit like a dress Marilyn Munroe might have worn. In short, this dress makes you feel like a goddess.
It is a good fit for a UK10. Fitted in the bodice, with a floaty, ethereal skirt and angel sleeves.
Sits mid thigh in length (based on a height of 5'7").
In excellent vintage condition. There are a couple of tiny marks (see photos) but given the print these aren't noticeable.
I would say it's polyester.
