The simple answer to this question is you have to be over 18 years of age. That really is the only restriction to the service 'undercover' provides.
Many, many women, far too many actually, think they're too old or the wrong size or shape to do a glamorous photoshoot. Fortunately, this is complete nonsense! I've shot with women of all shapes and sizes, the results were always warmly welcomed. I have permission to say that the lady in this pic is in her mid-50's, and looks sensational in my opinion.
I firmly believe that beauty and glamour come from within, all any woman has to do is feel it and it's then up to me to capture that essence in a photographic image.
There are so many gorgeous women out there that don't fit into the mould of today's media concept of ideal beauty. Well, so what? Every woman has her own beauty and deserves the opportunity to let it shine.
