Myself, I'm a big believer on beauty being on the inside. My man can be the hottest thing at first glance, but if there is no beauty inside then, his outer image becomes distorted. To me inner beauty brings out or intensifies outer beauty.
My choice is inner beauty. Inner beauty makes anyone hot. Outer beauty is nothing but pretty packaging. For example, You can wrap dog sh*t in silk; The silk is will look nice but it's still full of sh*t. : )
