In this era of selfies and social media, most of us turn into super critics when examining photos of ourselves. To present your best self, let's start with clothing choices. As you can see from Katrina, a midi-length, flowy dress creates a lean look. When paired with pointy-toed heels in the same color tone, the viewer's eye is drawn down without cutting her off at the ankle with straps. The net effect is a lovely, lengthened appearance. Aliaa, on the other hand, wears a dress that doesn't really do petite people any favors.
