If you got to the one site www.dancer.com, click on their links then click on miscellaneous resources, you'll find a whole slew of dancewear websites, one of which may have a photo of a guy in a red leotard. The trend over the last few years for male dancewear has been towards darker colors, so I think you may have a problem finding an example in red to show your director.
Some of us have libraries of dance photos. I don't know if I have a photo of a guy in red online, but will look.
NYDancewear seems to be the most reliable place on the web for men's dancewear. They may have to special order exactly what you want, but I know they'll custom order whatever.
