The latest challenge: creating cocktail dresses inspired by, none other than, cocktails! Tensions run high with designers vying to put their dress on host Alyssa Milano, the prize for the best look. To win, they'll have to stand up to the test of guest judges Nate Berkus and fashion designer Rebecca Minkoff. When these designers are through, they'll definitely need a few cocktails to unwind. Be sure to tune in on Thursday, Nov. 7 at 9PM EST on Lifetime (opens in new tab)!
