Too cool for two strap?

I seriously must have been at school the last time I was FORCED to wear a backpack and now 6 years later I am actually choosing to wear one. I picked this little fringe tan bag up in Primark at the weekend and I thought it would come in handy on those days I can't actually be bothered with an arm crippling handbag... Oh and because I thought it was super cute!
