my husband is very slim but I also have trouble finding clothes as he is 6'6" tall with a size 13 foot, and most of the local shops seem to assume if you are tall then you are also wide, which of course isn't true! We buy a lot of clothes online from specialist stores like kingsize and bigguy but it's a real shame as the bargain target stuff is usually unsuitable and he can't find cheap runners for wearing to work anywhere because being a carpet fitter he wears the toes out within a month or two no matter how expensive the shoe. He used to get $15 ones from target and k-mart but they no longer sell up to his size.
