red or brown???

So I have a hair appt on December 5 and I have no idea what to do. The above picture is my current color...very light brown with alot of highlights.

I adore Kate Beckisales look...her hair color and her makeup. It's obviously a darker brown...probably closer to my natural color!

However, for about a year now I have wanted to go red. I don't know why...I guess because I might as well do it now in my 20's when I can get away with trying new things. Plus I tend to have red undertones in my hair anyways.

I am so torn...brunette would be easy upkeep while I hear that red tends to fade easily. Please grace me with your opinions!!

PS: The above picture is kinda silly...we were playing in leaves like little kids!!
