I would say this:  In order to achieve images consistent with my portfolio, there are three things I’m very specific about:  location, time of day, and clothing.  Changing even one of these things will yield images that are different from what you see on my website. I encourage you to borrow from the Studio Wardrobe or allow me to shop for you.  I always recommend light, neutral tones.  In the end, you can wear whatever you would like, BUT the whole vibe of the image drastically changes to something different than what you loved about my work if you incorporate darker colors.
