I love that beautiful old desk (and totally wish that mine will look like that! Well, I can hope) and the layout of these beds. Plus, blue is totally in my color scheme, so its nice to see different shades of it implemented so well in a dorm room.
The stripes, which appear to be painted, are actually stickers called Wall Pops that can easily be removed and are very affordable!
Chevron and thick black borders. Add a splash of turquoise for that in-style color block feel. Genius!
