Here's my take on Cyclops in his classic gear. This was the costume he sported back when I was a kid and despite being simple, it was a striking costume back then and still works today. I took a DCUC Guardian body and added Dr. Impossible gloves. Red Tornado boot cuffs were placed on top of some Flash lower legs so his boots would look nice and thick.
The head was the most challenging in that I ordered two ML casts, one with the classic visor and one with his modern visor and neither was a good fit; one too small, the other too big. So I dremelled down both heads down to just the visor and ended up using his classic visor on a modified Guardian head. The belt buckle was made out of styrene, equally challenging but nothing a little patience couldn't cure. A nice paint job and dull coat later and here he is.

Edit-Modified visor to be slightly more accurate. Sliced main visor from the ear covers. Sanded down the visor to shorten it as well as round it out so that its less flat across his face. Placed it a little higher on the head so his nose is better exposed. New pics uploaded.
