AR, that is a good casual look.
Others have said this sort of thing before, but he looks proportionate to me. I am blind to whatever the problem is.
Thanks. Re: proportions I am a bit thinner on top, enough that if I wear a normal-fitting t shirt, slim jeans and rafstros with no jacket or anything, the result is bottom-heavy. If I'm not wearing really bulky footwear though (ie, bulkier than Lanvins) it's not noticeable.
