How big is a Juicy Couture Day Dreamer bag?

I have found the PERFECT juicy daydreamer bag for school! its navy, white, and light blue. it looks great with all my clothes too. The only thing is, my school has a rule about purse size. A purse cant be bigger than a 8.5" x 11" piece of computer paper. Does anyone know how big the average juicy daydreamer is? 10 points for the most detailed answer!
