What to wear (and what not to wear)
Wear what feels comfortable. You're the star of the show, not the clothes, so the key thing is to avoid distractions.
That's why I always suggest avoiding neon and other bright colours, loud patterns, slogans or logos, cartoon characters, anything that is going draw the viewer's eye.
There's really no need for everyone to wear matching blue jean and white shirts, but you can if you want.
Please don't wear glasses that go dark in the sun (photochromic/Transitions). It means we can't see your eyes.
Men, think about facial hair. The camera can tell the difference between clean-shaven and five o'clock shadow.
