^lol! Linh! My friend goes to school with her xD
Honestly, I think that hairstyle has been way overdone and it requires alot of maintainence/teasing/volumizing products. Though, I think it would look nice on you.
You have suitable face shape for a nice angled bob. Its very classy and chic, but that's just me and I have boring taste xD
Whatever you choose have fun with it. It's just hair & it'll grow back.
