The Too Faced Natural Eye Pallet is a great choice for natural eye makeup. There are three different looks and instructional cards on how to apply the eyeshadow as well as where and what order. It's great, i use it everyday for work and yes- - even at my graduation!
Congraulations on graduating, that's a great accomplishment. Don't forget to pair your eyeshadow with a primer (I like the Too Faced Shadow Insurance). It prevents it from creasing and makes sure it stays in place as long as you need it to!
