where to get a suit?

so….. i think the only suits i’ve worn were ill-fitting, 2nd-hand, worn only out of necessity for some occasion i didn’t even care to attend. but i’d like one now. i’m not about to get any taller, and i’m not afraid to pay for some sweet threads. it would need to be tame enough for business, slim and stylin, hardy, and easy to keep clean. think if carhartt or dickies made a suit….

where do i go? (besides instructables to learn how to tie a tie)
