Princess Eugenie must have a fantastic dry cleaner.

The young royal stepped out last night to attend The Boodles Boxing Ball in London wearing a gown we just saw her wear in July. The floor-length dress is a pretty high profile repeat, considering she just sported it at the glitzy Novak Djokovic Foundation inaugural gala dinner two months ago.

Luckily, the 23-year-old looked lovely in the simple number as she joined her boyfriend, Jack Brooksbank, a glowing Pippa Middleton, Prince Harry, Nico Jackson and Cressida Bonas at the high society social gathering.

Moral of the story? The next time you're stumped for a black tie event, try shopping your closet -- it's what princesses do, after all.
