I'm trying to get something to carry my macbook and a few books for a postgrad course (such a great reason to get a bag). I want to look sophisticated yet studious... but not in that legally blonde (Reese Witherspoon) way but more Ann Hathaway. Which of the tote would u choose? The first 2 are magnetic closure, the right most is zip closure. The left one is the most pricey, the middle one is 100 less, and the right one is 200 less than the most pricey. Thanks gals!!
