Get a body (for a beginner customizer, 1/6 scale is best, but you can get a bigger one just fine for a more source-accurate appearance), get some fabric and ribbons, specialized paint (though really just watercolour pencils are fine) and sealant, get some synthetic hair, look up some sewing, accessory-making, face-up and wig-making tutorials, make her dress, make her wig, make her headband and shoes, paint her face, you can have in-set eyes or just paint them onto the head, that depends on the head type, but basically, you'll have her ready for any sort of action then, and she will do your bidding as you please, it is only natural for a doll.
Or you can get a readymade custom uuuhh dollfie dream had rozen maiden ones but that's more expensive and less fun/erotic than doing it yourself
