I absolutely adore things like this! I think this room is very pretty and I would love to have it! Interior design is actually one of my favorite things. So, if you have any reservations with doing your room the way you want it, please don't. It's okay to be like "other girls." I reiterate, most girls are fantastic! There are always going to be people who will be hateful about things that you like, but that's their fault.
Here is a playlist to listen to while redecorating your room:
Miss Independent - Kelly Clarkson
How It's Going To Be - Gerard Way
Love At First Sight - The Brobecks
Blank Space - Taylor Swift
Since U Been Gone - Kelly Clarkson
Bulletproof Heart - My Chemical Romance
I Don't Care - Fall Out Boy
Defying Gravity - Wicked
Funny You Should Ask - The Front Bottoms
