I my Twiggy!! I'm 5' 5" and I think it's the perfect size ... not too big, not too small. I looked at the other styles, but this is the one that caught my eye the most.
I have a cornflower blue, a black and a camel twiggy. I Love the Twiggy style! It's roomy without being too big. It fits my shoulder, and the items inside don't shift. I highly recommend them.
