It's the way it goes nowadays, unfortunately :shrug:
Anyway, my characters have very distinct dressing styles:
"Assassin", Great Khan simple armor (look great on her and black is her color), Reinforced Chinese Stealth Suit (more stylish and useful than the default Hei Gui suit).
"Tesla Tank", Wasteland Doctor or Followers Labcoat (the obvious choice, being skilled scientist and a doctor), Dragonskin outfit (with Winter or Medic camourflage, occasionally NCR camo too).
"Heavy", Merc Grunt outfit (simple and practical), Dragonskin outfit (camourflage color depending on environment) and later a T-51c Power Armor (modded, like a hybrid between T-51b and APA2).
They all look great on their respective characters
