While there was no prom in Harry Potter, there was a Yule Ball for the Tri-Wizard tournament that featured some quite memorable formal wear. This year at prom, this delightful couple took advantage of the styles of Ron and Hermione, courtesy of the great sewing work of DeviantArt user TheDeluxeWar.
In a way, these prom outfits are a lot better than typical prom wear too because the lovely couple will get to rewear the clothing at the Otakon convention.
