Well, most girls who start off in camming, generally do not have a bunch of toys, compared to veteran models.  But yes, to answer that question.  New girls can just look around their rooms and use what you think can work.  Simply enough a cute bra and panties.  Perhaps even a tank top, if you have mini skirts.  Years ago, a lot of girls had worn more lingerie than today.  We seem to mostly go with the cute more realistic costumes.  Tank tops with or without a bra to show off that cleavage while you are sitting on your desk or lying on your bed.

We know that while we are online working cams, our toys get dirty.  We are cumming on them, inserting them in our mouths, pussies, and assholes.  You can clean up with an Anti-bacterial soap between shows.  Yet, that may not be the safest to do.  You need to inspect these toys and make sure they are safe.
