That is really interesting, I think you might be right. I am going to try on some of the lighter/diff coloured bags.I love M/L size and I'm not overall a fan of big purses. I think sometimes black can be such a contrast that can make it look larger. I recently bought a reissue 227 in grey and somehow to me, the neutral color makes it look smaller. I also think that the black/gold combo makes an even larger presence.
If you aren't sure, I'd try the Jumbo or even a 227 reissue in different colors.
The grey in reissue sounds amazing!Did you get in gold or silver hardware?
I've been coveting the 'taupe' flap a few seasons back. I would buy it in a heartbeat if it ever came back =)
