First Of all, basically the base, Paint your room. But yeah yeah I know this isn't a must because I don't think much people would go through the hassle and struggle of painting their room especially if they don't own it and maybe rent their house. But if you can and want to a Nice colour to paint it would be PINK. That just in my opinion because I LOVE PINK!!!
The Next Thing after painting your room, get a nice comfortable bed to sleep in. This just because like..you wouldn't buy a bed that you don't like. But if you're not going to be buying a bed Look Into the next Tip after this.
If you're not going to be buying a bed anytime soon, you might at least want to decorate your bed. One thing I would suggest is putting a throw and a lot of pillows around your bed; The more the merrier. Then You Could Put some fairy lights on the headboard of your bed but if you don't have one stick up fairy lights {Using sellotape} around the area where your bed faces.
This above is an example of where to put fairy lights {Normal LED Lights} If you don't have a headboard. Just lace it all around the ceiling of your bed to a little bit down the wall.
One thing I like is to have a pair of fluffy slippers at the bottom of your bed. They don't have to be fluffy just so that you can like hop out of bed put on your slippers and walk around. Examples are below:
Examples of fluffy slippers{You can use ordinary slippers}
Next thing you can do is to get a makeup desk and line up all your makeup products on the desk and maybe use the first 2 drawers for makeup and use the rest to store socks and underwear.
Another thing you can do is to Use your windowsill for placing nice things like perfume and lotion and other things like that. For instance, these 'Victoria secret PINK' Perfume and hand cream Would be really pretty to put on your windowsill. Examples below:
The last thing you would need and would probably want to put in your room is your name over your bed. This is a really fun and decorative way to brighten up your room and give it life.
