24 & contemplating gray hair streak

I am a Puerto Rican with a tanner complexion and have long black curly hair that reaches almost to the bottom of my back. I am about to enter Grad school in Aug. and wanted to give myself a little more distinction and character with my hair.

I was thinking about getting one streak of gray kind of under my hair on the right side- since my bangs swoosh to the left. My problem is that I have never seen anyone do this before, so I am wondering if this is just a bad idea, and if anybody has any other suggestions?! I want to avoid high maintenance all over highlighting, and looking for something a little more artsy since I'm a graphic design major....

Thanks!!

Yeah, you're probably right. The only images I can find of such things are Bride of Frankenstein wigs!! haha

I'll probably opt for some dark auburn low lights instead. :/
