I usually enjoy a casual combo, so I like to use a pair of T-shirt and jeans for my character in open-world games. However, Niko Bellic in GTA:IV looks better with a suit style combo (from Perseus, of course) and GTA:IV doesn't really have good casual clothing in my opinion. A tuxedo on Niko Bellic looks better. As far as The Lost and the Damned and The Ballad of Gay Tony are concerned, I play them in their default clothes.
