IMO, i feel that structured bags like a kelly or birkin in green would look a bit "unusual" if the size of the bag is too large. I have seen an emerald green croc kelly in 28 cm and we (as in my sis and I) share a 28 cm Vert Anis Kelly. In this "smaller" size, the green bags are nice... but anything larger...hmm... (this is my opinion only)
I completely understand what you mean. I think that's why I would lean toward a darker, more-neutral green, such as forest green, for a 35cm Birkin. And that's why I was hoping for some real-life-sighting advice about which particular shades of green might work for me--and which might look like a "bit much."
