Hair Color Advice - Blonde Under Brown?

by Tayy

I've been thinking of getting blonde under my naturally brown hair. My hair is kinda short (like shoulder length), I have short layers, and I straighten it. My hair is pretty healthy, so I'm not worried bout damaging it or anything. I'm just not sure if the the blonde underneath would look okay on me.

I want some blonde in my hair, but I don't wanna look (no offense to anyyone!) really preppy. Is there anyway I could do that, and have a punky edge to it but not going over the top? Comments and answers are appreciated!
Thanks.
