make your caw in just a bikini then change her skin tone to 90x9 then edit bikini colour to 90x9 and that should work. BTW this is a guess since ive never done this before, im not a perv just answering questions on here that i know ansers to.
The multiples of 9 arex9=9x9=18x9=27x9=36x9=45x9=54x9=63x9=72x9=81x9=90x9=99x9=108
