Here is Matt the Mysterious Raccoon as he explains the 4 styles of customers

Style A: The Customer's default outfit
Style B: The Customer's Alternative Outfit after unlocking the 3 stickers corresponding with the Customer
Style H: Holiday, Only the 12 customers who are unlocked with a holiday have this outfit, alongside all 7 closers on Halloween.
Style N: NAKED, this would never fly in the Papa Louie because Matt Neff and Tony Solary wants to make these games suitable to kids, but there are people here on Weasyl who like Naked Furries.

This stuff is mentioned on Raccoon wire clip Who let the dogs out,
