I've recently retired after a 30+ year-career as a photojournalist, and corporate photographer and college photo teacher. Like Max, i've photographed many subjects in the studio and dealt with many background problems and possible solutions for a long time.
I don't recommend using a white background for model photography unless the photographer is using a rather sophisticated camera and has lots of experience. White is probably the most difficult background to use well. It can create a wonderful photo, but for casual picture takers, it can often lead to disappointing photos.
For most model work, a light to medium blue often creates the most pleasing results for the casual shooter.
Human eyes are used to seeing things under a blue sky, so any reflection of blue onto a photo subject will often appear natural or at least acceptable to the eye.
There are of course exceptions to the rule, but my experience has shown that for the "quick and dirty" model photographer who doesn't want, need, or can afford really sophisticated cameras, lenses and lighting gear, a simple blue backdrop is a very successful set-up.
I most often use a blue background for model photos I've posted here on the FSM forum.
Just have fun with it. Simple is often the best way.
