For the main character you need 1 level of monk or barbarian for unarmored defense. Go the rest of your levels in blade singer wizard. Use the stat boosting very rare items to get dex, int, and either con or wis, depending on monk or barbarian, up to 30. Get bracers of defense, a defender, and cloak of protection for your attunement slots. Without blade song your AC with be 10 + 10(dex mod) + 10(con or wis mod) + 2(bracers) + 3(defender) + 1(cloak)=36. You would blade song on your turn to get an ac boost equal to your int mod so your ac goes to 46 and cast Alustriel's Mooncloak to get half cover for +2 ac up to 48. One of the characters helping you cast shield of faith on you to bring you to 50 ac. The second is a valor bard that casts haste to bring you up to 52 and gives you a bardic inspiration die for combat inspiration. The last character helping is a cavalier fighter with enough levels in cleric to cast warding bond and still be ready to use warding maneuver. That would make your ac 53 + 1d12(defensive combat inspiration) + 1d8(warding maneuver only if they still hit) +5(the shield spell) for an average of 69(nice) and a high of 78 all without armor or a shield.
Rules:

Use the Barbarian option, take a shield +3, and your AC goes up by 5.
