You have started several threads now about these bags, you can just keep asking question in one thread. No need to continue to post new ones about these bags. ; -)
I've also only seen the mediums. If I saw a large, I probably would have bought it instead of the medium. BTW, the Nordstrom near me have the Blue and Black of the medium. Haven't seen a choco IRL.
I bought my chocolate silverado large doctor at Saks-Houston during their gift card shopping spree day. I tried on the hobo and I think it must of been a large because it seemed as large as the doctor I was buying. I just liked the doctor style over the hobo. Saks-Houston seems to have a nice collection of Chloe.
