Making your boyfriend's wardrobe work for you.
My boyfriend is tall, thin, and athletic, while I'm short, thin and athletic. The similar body types means our sizes are close enough that he can't wear my clothes, but his look perfect on me when belted. If you have someone like this in your life- boyfriend, brother, friend... Borrowing their clothes is a great way to maximize your (and their) wardrobe. I've been doing this for years. :-p Worth it!
