Ahhhh.... I am looking at a Betty chain hobo... it has one chain strap, not the double leather straps. I had the medium Betty with the double straps a long time ago, and the straps didn't work for me. Too wide and wouldn't sit on the shoulder, kwim? But the chain strap hobo might actually work!
ITA about store SAs... I've been in the MJ boutique before and asked them about bags, and sometimes they don't know the color names or the bag names either. Once in a while you run into someone who knows their stuff, but it's very rare indeed. This discussion reminds me of Retail Hell, a book I read recently about a SA's experience in handbags. It was a funny book and interesting to read about the SAs perspective.
Ahhhh - I know which one you are looking at!! I was eyeing that, too - it's gorgeous...I lurve the Bettys with chains.

I would also love to find a medium Betty in a color like gray or patent bordeaux. And I'm gonna look up Retail Hell!
