If you're fortunate enough to live with a roommate who wears the same size as you, sharing clothes and accessories can basically double your wardrobe! But to make sure you don't make anyone mad, check out Lauren Conrad's tips on #SharingACloset.
First of all, ALWAYS ask first! Never borrow anything without asking. Even if you're just sure they'll say yes, you need to get permission before even going into their closet.
Second, return the borrowed item in the condition it was in when you borrowed it. Wash it or dry clean it before you put it back. Be sure to return it in a timely manner. You need to do the same for all shoes, purses and accessories as well. Clean dusty shoes, wipe down purses, etc.
If you damage something you borrowed, repair it or replace it before returning it. Also, own up and be honest, don't try to hide what happened.
