I think that you should cut it just a little bit cause it's too long and after cutting it, you may dye it with brown if you want to...but your hair is beautiful, besides it's a good if you have a guy to hold your hair and smell it and tells you how nice and fresh it is:)
I like it how it is now but if you wanna cut it then go for it. Short hair on girls make them look older. I know this one girl who had long hair like yours. Then we she cut it short, like shoulder length, she looked like a mum lol. But she still looked gorgeous.
ughh your a veryyy pretty girlll...im jealouss hahah but anyway to the hair... I like your hair that length, but maybe you can cut it like three inches. and dye it like a light brown to like a medium brown.. Do what ever you like hah... but don't change colors to quick if you want to go to like dark brown like mine gradually fade it darker. I think dark hair would look good on you. but then again its my opinion and your hair. the choice is up to you.
