Nudity is often preferable.
As is dispensing with armour in the video game, sometimes... It's a quirk of 5e design, carried over here, that Mage Armour, if you can spare it, is as good as +1 studded leather; what this means is that if you have light armour wearers, unless you have access to +2 studded, or an armour with a particular benefit that outweighs the AC, Mage Armour alone will provide you better protection. This goes further: it's also flat out better than hide in all cases, equal to chain, and if you have a +2 dex mod, it's better than some heavy armour as well. If you have +3, the only armours better than mage armour at base without enchantment are Half-Plate (medium), Splint (heavy) and full Plate (heavy). Mage Armour is, of course, lighter than all of them ^.^
