An exquisite shirt (60 points), exquisite pants (60), exquisite skirt (60, and yes, you can wear it with pants), exquisite shoes (40 points), an exquisite robe (40), an exquisite belt (40), extravagant gloves (20 points each, but mutually exclusive with gauntlets or bracers), two exquisite rings (120 points each), and an exquisite amulet (120 points again) will give you far more enchanting opportunities than any armor. If you want to attach powerful enchantments to ordinary wearable items, though, you want to focus on clothing. The best generic armor options without regard to weight are the Daedric Cuirass (60 points, heavy), Telvanni Cephalopod Helm (100 points, light), Imperial Chain Pauldrons (7 points each, heavy), glass greaves (10 points, light), Daedric Boots (26.3, heavy), Daedric Gauntlets (60 points each, heavy), and the Daedric Tower Shield (225 points, heavy). Pauldrons are uniformly bad (no more than 1.5 points each). If you want to enchant light armor, the best pieces are glass cuirass (12 points), Telvanni cephalopod helm (an astonishing 100 points), glass greaves (10 points), glass boots (10 points), glass or chitin bracers (10 points each), and a glass tower shield (45 points).

Most of the light and medium armor tops out at around 20 points of enchantment. Also, immediately after you start out, you can ride the Silt Stiders (travel bugs) to Vivec. Make sure you save before attempting this. You will have a good fight and someone may see you. Then, kill one of the Ordinators in Balmora.

Armor's actually pretty lousy for enchanting. To get good armorer at the start of the game, get very proficient with one weapon.
