Sigh. Why couldn't we approach the end of senior year equipped with as much fashion sense as the great Lily-Rose Depp? The 17-year-old It girl [1] joined her friends on prom night in the perfect peach silk dress. It wasn't too flashy, it didn't take on trends too bold, and Lily-Rose will certainly not regret her choice.

Thanks to the gown's iridescent shine and subtle texture, Ms. Depp stood out from the crowd, even though most of the girls chose maxi silhouettes too. When it came to accessories, Lily-Rose kept things simple, completing her look with a dainty necklace and toting her white iPhone. Read on to catch another look, then jump in the nearest time machine and redo your own high school dance. We suggest shopping beforehand with an on-the-rise model [2] like Lily-Rose.
