Just gonna piggyback and say: Banded Armor, Mail Shirt, to begin with. Banded's a bit out of what I consider medium though.
For low-to-mid tier: Ragged Outfit, Mail Shirt, Mail Shirt with Fur, Byrnie, Heavy Aketon, Cavalry Robe/Dark Cavalry Robe, Palace Guard Armor, Druzhina Mail Shirt, Haubergeon, Eastern Lamellar with Jacket and a lot of the Surcoat/Heraldric stuff in that tier looks pretty okay on the female model.
