What's a good backpack I can fit my macbook in?

Where can I find a backpack that won't make my dresses ride up?

• Help me find a dress-friendly backpack I travel a lot for work, and because I often wear dresses, the large Case Logic backpack I currently sport often has me unintentionally flashing people. So, I'm looking for a backpack for a small woman (I'm only about 5' 1") that will not continuously ride up my dresses. It needs to be able to fit a MacBook Air 13" laptop and preferably double up as a travel backpack for carry-ons. Extra points for stylish: I really hate the standard black mesh look for tech goods. I'm also open to awesome laptop handbags.

  I was in the room when a bunch of people started talking about this. They were universally short women in college. The conclusion was that this happens when the backpack is too long for one's torso. If the backpack dips low enough with each step to touch the top of the buttocks, then it can drag one's skirt upwards as it rises. Their solutions were - wear pants - carry a backpack-sized purse (I think that one was developing shoulder pain, though, so don't do this) - carry a messenger bag and cinch it tight like she was actually going to ride a bike, so it stayed up high across her shoulder blades - carry a messenger bag and let it swing loosely around her knees - use a hiking backpack with adjustable torso length One of them also mentioned that after (for some unrelated reason) she sewed a chain into the hem of one of her skirts, it stopped happening with that skirt.
