I'm a sneaker kind of girl, even in the summer. I prefer a pair of low top white Converse to sandals. For the winter I got a pair of riding boots & snow boots and I was set.
As for handbags, I don't really like them. My mom got me a Michael Kors crossbody for my birthday and I kind of felt bad cause I didn't like it? Lol. I still wear it when I go out with her tho so she won't feel bad.
But I use this as my school bag (in black):
Got it from H&M and it's the perfect size. So much space. Fits my iPad, my 2 folders and my notebook. My 13 inch laptop and more could fit in there. I remember they had a weekender version which was much bigger and I still want it.
