It is slightly diffrent but i think it would look lovly.
(i hope you don't like in the UK or you might as well just buy some wellies and a trench coat)

that would look reeeally cute :]
well, i saw a short sleeve grey pea coat in forever 21. it wa longer then the average coat and would be just delightful for spring! so maybe something along the lines of that? hope you find one, good luck
