yeah, 5'9", 145lb guy here.  29-30inch waist.  Can find 29-30 inch waist pants but they're ugly.  If it's pants that I like/want I have a devil of a time finding pants in my size.  If I can manage to find an appropriate waist size then the length is too long (30 waist 30 lengh is the ideal fit for me) The sizing of the waist seems to depend on brand/manufacturer.  Some 30 fit fine while other brands are a bit loose. Finding a decent slim fit SHIRT is a different story.  Very rare to find a nice shirt that doesn't billow out at the stomach like a maternity shirt.    Disgraceful. edit: my girlfriend sometimes buys me clothes from Hong Kong, they seem to fit better for a guy of my size.
