I just went through this dilemma myself. I preferred the look of the 226 on me but was worried it would not fit enough. I went to the boutique and brought my largest wallet, pochette, and a few extra items I sometimes carry. Everything fit fine in the 226 - a little tight but that was the max I would ever put in. So, I went with that one. It is a little short on me crossbody, but the 227 was about the same length.
Ultimately, I knew I would be happy with either one since it is such a great bag. I do think both look great on you!
