Learn from me:
It's a really dark grey fabric with lighter grey and dark red/blue pinstripes (the blue and red are not very visible but add much to the pinstripe effect). It was 15 dollars a local thrift store. The shirt I got at Kohl's for 30 and is Herringbone Twill. Shoes are just plain black semi-shiny Nunn Bush from Kohl's as well. It's a Docker's reversible belt that I got for 8 bucks from Kohl's clearance.
edit: Oh, and the tie is a solid grey tie that is 100% polyester, semi-shiny. I got it from my dad's wordrobe, don't know where he got it, but the brand is called "Botany'500'"
