Yum, candy corn! One of everyone's favorite candies, I'm sure!
This one's easy to do. I started out with MAC Vestral White as a base, then used Zoya Sienna for the orange, and Milani Yellow Whiz for the tips. It was a bit too many coats though, so next time I'd recommend doing the entire nail orange and then adding the white and yellow on top.
Of course, I just had to buy some candy corn for the picture and ended up eating almost the entire bag.
