As a costume one of the best ever taken too bad that it's not Doc for my body. Very valid!
Initially I was reluctant to buy this model but once I arrived I immediately fell in love with the color, in the sun it is gorgeous.
I carry a 2nd B and I have always taken an M of the other models but this one is slightly big even if I squeeze the shoulder straps to the maximum. But it's not too annoying.
Probably the S would have been small so that's okay!
