Well I've done Naked Snake and I noticed that I have alot of the gear to be able to make Snake from MGS1. Snake looked more hardcore obviously in no2 XD but the costume from the first game was just so awesome!
Techinically speaking, now that I look at it, all I really need for this is a new black bandanna. But I reckon I may go all out and get elbow pads and a new assault est to go over the armour.

Now where's that cardboard box...
