Creatable World was a short lived concept - as many of Mattel's specialty series. These dolls are gender free and you could implement whatever you wanted to them. The dolls all have the same features but come in an array of skin and hair colors. They all have rooted hair, but in a short do. Each doll come with a wig to give them longer hair.
The (first) DeLuxe sets includes a lot of fashions, shoes, hats, bags etc to mix and match. In the second DeLuxe round, the bag was omitted and the box design was slightly simpler. A series of six Starter sets included the dolls and wigs from the first series of DeLuxe sets. No fashions. Which leads to the separate fashion and wigs sets for more creative playtime fun.
All in all there are nine different dolls in the total of 15(?) doll sets. Fashion sets in different sizes, the wigs was sold in twos and there was a wardrobe announced. Some advertised sets have never been seen, so probably not released - or just hard to find.
