Wow, I actually really like 3 of the 5 examples in the OP. Reinforced Combat Armour Mark 2 looks bitchin' when coupled with a rebreather. My favourite aarmour loadout in New Vegas is Reinforced Combat Armour Mark 2, rebreather, and First Recon Beret. You look awesome.
OT: Bayonetta's retarded hair/suit thing is the most hideous video game outfit I've ever seen.
EDIT: I forgot to mention the Helm of Honnleath from Dragon Age: Origins. It's the most heinously ugly helmet I've ever seen, but it's bonuses make it too good to pass up. +2 to all attributes, +3 armour, and a natural 1.5 armour, which is quite good for a helmet of its class. I can't find a picture, but a description will do. It has wings on it. Big metal wings that stick out like weird ears.
