According to the show The Doctors (so decide whether you believe this for yourself) to find that perfect shade of lipstick for your lips? Just check under your bra.
Apparently, board-certified emergency medicine physician Travis Lane Stork, M.D. says that nature knows best and in order to find the right lip shade for you just match it to the color of your nipples!
Little catch though as the doc admits it won't work for EVERYone. If you're extremely fair or dark skinned you might want to go a little darker on lipstick because the exact color of your nipple might wash out the color of your lips.
So, are you gonna try this???
