In general, take full plate, then remove the smaller plates near the vulnerable areas. You have the Breastplate still, you have some shoulder and bicep coverage, forearms and typically gauntlets, but the inner elbow is chain, you have the groin/front of the thighs covered, but the butt and back thighs are also just chainmail or just padding.
