Well personally i use a combo of sunspear top and shing jea everything else. Its cheap and i look really good. Male obsidian looks pretty good, but its very expensive.
Personally, 15k Luxon will always be my favorite with 15k Necrotic coming second. Just browse through the armors, full, mix, it's your choice in the end.
My male Necromancer is wearing Elite Luxon right now and he'll get Elite Canthan next. Personally, I prefer the armors that don't expose the neck or chest area because male Necro skin is creepy looking, unlike their female counterparts.
