Hi, I've got one Chanel (pink PST) & have been contemplating adding a GST in black to the collection. I am in Kansas City so there is NO place around here to check them out. So I've got a couple of questions. First, what are the dimension of the GST? Is it a lot bigger than the PST? Second, I would love to see a pic of someone wearing the GST. I am 5'2" & about 110 pounds & would love to see about how big it would look on me. I love big bags so I doubt that it will be too big.... Thanks!!!
