Started a new thing at my photo studio in downtown Edmonton, Canada... weekly theme specials. First one is for Wednesdays called "Wig Wednesdays", giving you 50% off photo shoots taken in your favorite wig, or you can borrow one of ours. The second themed special is Hat Attack Thursdays, which gives you the same deal but with shoots sporting a chapeau. Makeup applications are also available at the studio for only $15 on those days (available for walk-ins on Wednesday, but you need an appointment for makeup on Thursday).
Of course this is a fantastic deal for cosplayers, who may be wanting to shoot in wigs and hats anyways. Why not get a huge discount while doing it?
