Nice bag from Kate Spade

I always like black and white theme so this bag appeals to me. And the size is not too small. But I think it is a open top bag so its out! Generally I prefer a zip top closure bag as things in my bag are always so messy and scare things will fall out easily. Trying using a bag organizer but after a while I'm back to square one! Lol. Guess a leopard can never change its spots.

So what sort of do you use or prefer?
