While my sister and I were in Las Vegas, I borrowed her lipstick one day and couldn't help but notice how different the shape of her lipstick was from mine. Our lips are completely different anyway, so I figured the shape of your lip must determine the shape your lipstick takes on. This morning, as I applied my favorite "Plum Baby," I wondered what your lipstick shape says about you. (Weighty thoughts like that often occupy my mind.) Lo and behold, I found a lipstick personality quiz via Google. Check it out here. My description is fairly accurate. Go figure.
