My turn to ask: which bag should I get next?

1. Hampstead MM - in Azur or Ebene
2. Galliera - in Azur or Mono

I have an Azur Hampstead MM and I love it. It carries a lot and it's so different from the usual black, grey, etc. and it is great for Spring/Summer. I use it year round, too.
I think the Galliera is a pretty shape. I don't have one but there are lots of great pics on tPF.

GL deciding and post pics!
 
I'd get the Galliera of the Hampstead! I don't think the Hampstead is too dressy, I think you could definitely carry it casually! Your extras sound great as well! Good luck with your handbag decision!
