Wonderland, you should say first what's your style. If you're more fancy, urban, classic. I've changed my whole bedroom without spending much, my mom is kinda crafty so we painted all my furniture in black, I love black/grey/white, so I painted all the walls in a really dark grey (almost black

), then I invested a little on a beautiful chandelier. My bedding's all white so it really stands out from the rest and makes it look comfy. Right now I'm making a wall of picture frames (that's a good idea, doesn't matter what's your style)... There's a buzzfeed section full of good tips, it's all about the details and not look cheap.
Here's a pic of my chandelier and a wall. I like it a lot.
