We moved my daughter into her dorm room at college this week and of course how she was going to decorate her new room was very important to her and to me as well. She looked for inspiration months in advance and we ended up buying a lot of things for her room at West Elm. There are a lot of rules around what you can and can't do so it makes it rather difficult to add decor...no nails in the wall or anything that can make marks...no painting or real changes to the structure of the room. We moved around the furniture as best we could and added pictures to the walls with washi tape and frames that were placed on the wall with a special velcro that can be removed without damaging the walls (we will see if that is true in about 8 months).
Here are a few ideas that can be adapted to dorm rooms....and my daughters room at the bottom. It still needs a few more pillows but we will add those soon....
