This will make you all but invisible as the traveling gear is what is equipped to you when your loading/changing areas like white fog. It turns you rather transparent and if you give yourself shaved hair you are barely able to be seen.
So to reiterate you need:
Hair Style: Shaved
Head Equip: No Travel Gear/ Head
Armor: Anything wearable but Chest Armor
Hands: Dragon Hands
Legs: Dragon Hands
Rings: Ring of Fog
Though you could probably make yourself even more invisible if you could find like a transparent value for hair and skin. Hope this helps somewhat.
