I purchased the Oscar de la Rental Fall 2017 Look 1: Hazel dress at a sample sale in October 2018, and did not end up wearing it or having it altered. The dress is an ivory color, with three-dimensional flowers and intricate beaded vines. There is a built-in corset which is suprisingly comfortable, and the dress is extremely flattering thanks to the corset plus the high quality fabric. There are a few imperfections in the dress which I took pictures of. A professional should be able to repair these and clean the dress.
Note that I generally wear a street size 4, sometimes 6, and this dress fit with some room to spare.
$5,000 or the best offer.
