The UD sale starts at 8AM Pacific today (9/15). If you'll recall, UD was on HauteLook back in May, but the offerings were pretty slim. To refresh your memory, there were just a few products available, and I believe that all of them were things that were previously discounted for the same price on the UD website, Sephora, and Ulta (Pulp Fiction palette, liquid eyeliners, etc.).
Fingers crossed that we'll see some new items today!
