Fatty Patty would be hard to buy clothes for that are super sexy. If she was in Hawaii she could wear the antithesis of sexy, the muu'muu. Those were designed by Christian missionaries as birth control. Till missionaries, we did not have the "missionary position" in Hawaii. It was woman on top, standing, etc. The missionaries did a good job of spreading this position by screwing the Hawaiian women literally and figuratively. The missionaries also came bearing gifts of the common cold, rubella, diptheria, syphilis, ghonorrhea, etc.
Anyway, blow up dolls are usually not a comfortable fuck. Look for the ones with fleshlight type mouths or okole pukas (assholes). Usually the more you pay for the doll, the better the quality.
I once saw a completely silicone Japanese doll which was all silicone and so lifelike but it cost 6 grand. I mean great skin, great hair, life size, cuddley......
On the other end of the spectrum, the least expensive dolls have the least features, scary mouths, sharp orifices, uncomfortable positions, lobster claw hands and they can leak or burst.
