So I recently downloaded the Sephora To Go app for my iPod and I just had to share with you how much fun I had with it! I'm a nail polish junkie, so this was really cool to play with. Midterms are coming up for me, so this app was a really good de-stresser. On the bottom, you can scroll through the colors of different polishes and the nails automatically change into the color you select on. On the left side, you can change the skin tone of the hand so it becomes more realistic and you can kind of see how the color would look like on yours.
