::who doesn't love a little whimsy?

So, we were talking at work the other day about celebrities we'd like to look like (yes, very productive and not at all shallow ;) ) One of the girls mentioned she'd like to look like Rachel McAdams.

1- Good choice 2- I completely forgot about her

I hadn't seen her in anything lately, but I got to thinking...remember the time she had pink hair?

Which got me to remembering how I always said I wanted to try this. :) So...should I try it this weekend or wait til vacation so I could leave it in longer? :) Second question, for those of you who have colored your own hair...is there any brand you'd recommend more?
