At first glance Ashlee Simpson looked like she was simply wearing another LBD (her closet must have hundreds of them) at the Conde Naste Traveler Hot List Party – yawn! Thank God we took a second look because the the close-ups reveal a stunning, detailed look that must've been spectacular in person.

The Philip Lim 3.1 dress is certainly an LBD but with unexpected details like a ruffled bottom, hidden pockets and triangle back cut-out. Instead of rocking the usual black or metallic shoes, Ashlee opted for a light beige peep toe to warm the outfit. Even her hair had a subtle but cool detail. Bet you didn't notice the little braid behind her bangs did you? And of course, her her big ol' diamond sparkler and long Chanel pearl necklace made us swoon.

By adding small but appropriate details each, Ashlee found the perfect accomplices for this look that could've been another ultra boring black dress but is far from.
