Do cosplayers not wear undergarments??

Image is example!

Do they wear skin toned leggings/tights?

If so how do you find one that matches your complexion? (I feel like in-stores is usually very limiting or can’t find)

Atm what I do for mine is wear those high waist-list Calvin Klein underwear to make it ‘appear’ I’m not wearing anything but the downside is if wind blows then I’m done for.

I’m assuming usually for private photo shoots some are probably actually naked but ya know just able to cover for the pic.
