This bedroom is from the Canadian House and Home website. I love the use of neutrals with just a pop of pink for some added colour. I also think the chandelier is an interesting touch; it's sleek. A small space like a dorm room can incorporate some of these ideas. Hanging your own chandelier is highly unrealistic, but the colour scheme is easy to recreate.
This next bedroom was found via the Lovely Undergrad. I love the use of light which is something easily emulated in a dorm room. I also love the clean lines. I desperately want that alarm clock, so much cuter than my cellphone alarm.
This dorm room featured on the Refinery 29 website is a lot bigger than mine (I could never fit a lamp, let alone a Greek column in my room), but again I think elements of this design can work anywhere. I like how pictures are grouped together. I think it's a little more personal than buying one huge poster to cover up a wall.
Another dorm room featured on Refinery 29, I love the wall art. They used Wall Pops, which are stickers for the wall, to create the stripes. I've been looking into decals for my walls to add some colour. I think this is a brilliant way to get around the fact that you can't paint the walls.
These images have really inspired me to create something beautiful out of my room. I would love to incorporate these images into my design. I think finding things that inspire you is a good first step to design. Now I just need to work on the follow through.
