I just received a classic short ugg from shoes.com, it is kids 6m(I called customer service and they told me it will fit size 6 in US adult), and I think it will fit me(my feet US size 6) too, but saddly it is too big, it would fit size 7 or 7.5 adult; So I need to do a return or exchange; I compared the kid and the adult ugg pretty much the same, and the kid's one is cheaper though....
