Birthday Surprise for boyfriend ;-) hehe?

If he's into the Trueblood show and stuff like that I would say go with your first instinct. You seem to be leaning more towards the leather one, but it also matter what you would be comfortable in.. do you like the leather one? If not then go with the other one. I'm sure he wouldn't complain about a hot girl there in a hot outfit for his birthday present :P
