My sneaky battlemage Bosmer, Serah Estiph, is wearing Vampire Royal Armor, an Amulet of Talos and the Nightweavers Band ring, Nightingale boots and Nightingale gloves with Nahkriin (the Dragon Priest mask that gives you 50 extra magicka and reduces destruction and restoration spell cost - this combined with the Nightweavers Band makes her Destruction spells cost 30+ magicka tops. Will eventually enchant something to make it cost nothing, but this'll do for now).
My Orc two handed warrior, Andromeda, is currently wearing banded iron armor, Nordic steel gauntlets and banded steel boots, perked a bit to give her extra protection.
My High Elf pure mage, Wren Mnemosyne, is wearing Novice Robes of Destruction, I believe, and iron gauntlets and boots for extra armor.
My Nordic Shieldmaiden, Nymeria, is wearing a full improved set of Leather Armor she made herself for the moment - she'll be heading Bashnag's way shortly to get Ancient Nordic armor.
My Khajiit sneak archer, Gypsy Moon, is wearing grey Vampire Armor, Vampire Boots and Leather Bracers (she doesn't like having her claws covered
) as well as a circlet that makes her archery do 15x more damage (all except the bracers were a lucky find off of a dead vampire in Whiterun's plains) at the moment, until she gets to Falkreath and joins up with The Dark Brotherhood to get something better.
And my newest character, a sneaky spellsword Dunmer named Ianthe Tinúviel, who will be a Vampire Lord when the time comes, is wearing a full set of leather armor with leather boots enchanted with fortify sneak.
And I think that covers it. Also yes, I edited this post to include all five of my characters and what they're wearing now.
