In response to were I got my Halloween Costumes from all information is here instead of a giant comment reply.
One thing to note is I unlocked hidden outfits to make some of these.
Frittata/Quorra: The only CC on Fritty was her hair. Link: Hair
Lettuce/Salad: Default pattern with colors changed.
Bonita/Cleopatra: Everything but the dress came with World Adventures. The dress is available through Dr. Pepper. Link: Dress
Bon Bon/Cheerleader: I can’t remember correctly, but I believe the cheerleader outfit was unlockable. Nothing on Bon Bon is CC.
Raspberry/Alice: Hair is from Ambitions, dress is from Dr. Pepper and the shoes and tights are base game. Link: Dress
Strawberry/Pirate: All from The Store and came with Barnacle Bay.
Juice/Chef: All unlocked career clothing.
Kix/Powerpuff Girl (Bubbles): Everything came with the game, but the skirt. Link: Skirt
Sabrina/Miller: All base game.
Bella/Jeannie: Bottoms are base game, top is Late Night(?) and hair is World Adventures.
Jasmine Rice/Hooker: All CC, but her shoes and stockings. Links: Dress Bracelets Hair Earrings
Steak/Woody: No CC.
Thor/Caveman: All unlockable.
Pat/Major/Captain Tony: All unlockable.
Lox/Washed up Rock Star: Outfit is unlockable (I changes patterns), hair is from The Store and tattoo sleeve, cigarette and black eyes are CC. For his drugged out eyes I made the black eyes completely black and used the least opacity possible. Links: Hair Sleeve Cigarette Black Eyes
I think that’s everyone. Let me know if someone was missed. I will double check everything when I can get back into my game.
