I'm guessing the Mafia Look or Elite Businessman no problem,
One style that grabs alot of attention is a powersuit (in Fashion Terms, go ahead google it under "men powersuit")it has stripes going down the blazer, including the pants, alot of CEO, Owners, and Millionaires wear these to work.
Another Style is the Mafia Look
target hold good Dress Pants Called Merona, it has Polyester/Rayon, Ive worked in autoparts store for about 2 years & they're still kicking, also they have a semi gloss shine that stands out alot!.
you can visit second hand stores (goodwill, second hand shop) ive came across High end vintage clothing that i get alot of compliments on, and you cant get anywhere else either (unique)you may have to dry-clean them though 
one blazer i paid 10$ value, real value is about 800$ made in italy, i actually drove 500 miles to find it, and the high end stores in Downtown San Fransisco didn't have it, eventually i found one in my small local town second hand shop...it was crazy!
some long-sleeve shirts 5$, real value around 300$..
i have to note that these two styles have to have the best shoes, if your shoes are not glossy or high end looking, the entire suit will fail..
on shoes you have two routes, research Italian brands & get them cheap on ebay used or buy some from your local store, i was fortunate of coming across some Italian shoes my sisters found in a yard sale, they are amazing...they produce no sweat in your feet aka no odor, but they up there though $300+ brand new.
its strange but people judge you by your shoes first before anything else...
