What is the best thing that i can give to my crush in Christmas Party?

If you don't know her that well, a gift card to a clothing store is always a hit with me at least. I prefer Old Navy or Gap personally. Gift cards allow the person to pick what they want rather than someone buying them something that will never be worn, exchanged or shoved in a closet. Beauty stores such as Bath and Body Works or Victoria's Secret gift cards work well also.
