There's nothing more embarrassing than finding out you're wearing the same thing as someone else at a party. It's even more embarrassing when you find out you're wearing the same thing as the walls. Let's face it, wallpaper isn't exactly a bastion of style. I don't remember the last time I saw some and thought, "that'd make a great shirt!" Now if you're talking about carpet, that's a different story. Get me a shirt with the same pattern as movie theater carpet and I'm in heaven.
This girl ended up with the same exact print on her shirt as this hallway, which actually doesn't look bad at all. Both her and the walls are working the hell out of that shirt. She's in luck if she needs to quickly hide from someone. Just press against the wall and hold your breath until they pass by.
