I have been trying to decide between the Emp. Artsy, Emp. Speedy, and Emp. Lumi all in black. Unfortunately they are all calling my name. I need advice from people that have experience with these bags. I thought I wanted Artsy. But today when I saw the black Artsy it looked so big and stiff. When I left I had pre-ordered the Speedy but when I got home I can't stop thinking about the artsy and Lumi!! Please help! Thanks so much.
