Please help me with the Hillier hobo!

I have the small one with silver hardware in black. It has a hot pink and orange floral lining, BTW. I got this bag at a REALLY great price cuz it had a broken 'O' ring, but then I had it fixed for next to nothing at Marc Jacobs. It's a really great bag, and I use it all the time. The cross-body option is wonderful. But...if I had had a choice (at the same price point) between the regular size and the large, I would have bought the large. I'm 5"5 and a size 4. I wouldn't say it's too small...I just would have preferred it in the huge size!
