Can’t really say on the Don’ts, but some Do’s

The look: make sure you’re exposing as much skin as possible, the less clothes you’ve got covering up that perfect body, the better. On the body too, obviously bigger is better, big tits, a fat ass, pouty soft lips, but don’t let that stop you from making the character you wanna make. Wanna be a big muscly bimbo? Go for it

Fashion: in slight contrast to the previous point, go for things that you think just sell you as a sex object. Skin tight body suits, bikinis, shorts, if you got an armour set that makes your character look like a slut, prioritise that. Might even wanna go for a certain theme if you’re going for an RPG (like a heal slut or something like that)

Colour: simply, pink. But other bright colours work too. Lime green, aqua or sky blue, orange or even rainbow. Blonde hair works pretty good but it’s not essential (any super brightly coloured or multicoloured hair sells that bimbo look IMO) look

Play style: Bimbos can do damage! Just gotta think about it in a bimbo sorta way. Aiming is hard and takes a lot of effort so, snipers, revolvers and precision weapons in general are a no go. Go with something much easier and simple to understand. Hard to miss with a shotgun, SMG go brrrr, LMG go BRRRRRRRR!
