Depends on what you use it for. For books, school, workout or travel it's great. To run around town, a Speedy 30 would probably look better. Love it though.
Is that the 50? I think you can get away with it - I use the 45 (would SO love a 45 Keepall in Damier sigh) quite regularly as an everyday bag for uni.
everyday bag ? I guess if you need to carry your house with you. No really, do you need the space of that keepall everyday ?
I guess I could see using it as a work/gym bag. having everything you need for the day but as a so called handbag no!
I think a carryall would serve better or a speedy 35.
