hm...from wat i can picture is that, a shirt (colour of choice, lines, or strips) with a dark slacks (nylon-ish can go well with shirt from Uniqlo) and a dark cardigan. IMHO, all these are fine, as long as the cardigan and the slacks matches well in colour, which is dark in this context.
The rest is about ur shoes and tie. I recommended black dress shoes and tie, because i dont know the actual colour of ur clothings, maybe u can play around with the colour of the tie, somebody advice on dark red tie, which is not bad too
Hope it helps
