Laptop bag for either 13" or 15" MBP

[sirkification]

I am a student who is planning to go to Uni. I'm trying to find a laptop bag that would carry my laptop as well as some chords (charger, maybe mouse) plus some books. I've tried looking but all I find is small bags with enough room for just the laptop. I want a good quality laptop bag with a good design. However nothing to big in size. Any suggestions for a laptop bag that will fit either a 13" or a 15"?
