Hermione Granger's Yule Ball Gown - Birthday present for girlfriend?

Honestly if my boyfriend gave me Hermione's dress from the Yule Ball for my birthday i would love it! If your girlfriend is as big as a potter fan as i am more than likely she'll be so excited about getting that dress she probably won't think anything except "OMG when do i get to wear it??" Cause thats what i would be thinking
