I thought they were all for sale at some Watchtower vendors. I've bought everything from them (skins, hairs, emblems, clothes...) However yesterday I wanted to use the "Bug Goggles" and I realized they were not available in my styles inventory. I re-checked those vendors and they were not for sale either. I had to create a new character with that face style, and only after that I could buy the style for main character for 1 replay badge. I don't know if this is a bug, if they should be available at those vendors, if I am missing any other character creation styles... If they want us to pay 1 replay badge for some of those character creation stiles, I think they should be all available to buy without the hassle of creating new characters.
