I'd hang on for the Mabel hobo. That style bag is still in the outlets, I've seen it recently in that colour & a pinky lilac colour. It is quite big.
I think its a very cute bag, i noticed it on ebay earlier I like how this colour is so unusual, a bit like brick red? Theres also a seller that has two available in oak on ebay right now.

I think the shape is similar to the 2007 sohos.
SJ you had a 2007 soho didnt you, would you say this bag is much bigger?
