What to wear to a photoshoot?

I was reading an article by Elizabeth Halford where she talks about wardrobe choices for child photography (Link Here), and that started me thinking about clothing choices in general for photographic situations. Again, there are a few simple rules that cam make life a lot easier for the photographer.

Avoid clothes with harsh patterns – vertical/horizontal stripes, herringbone etc. because it distracts the eye from the subject
Avoid outfits with too much contrast. A black top top and white bottom will mean you either underexpose the top, or overexpose the bottom – either way, too much contrast for the camera to handle
“Fun” ties or t-shirts with garish patterns? No. Further explanation not required I hope?

In a studio environment, while you can control light, you still have the same problems. I’ve noticed a few things as well.

In Hi-Key environments when you have a very light background, dark coloured clothes will over expose and you’re left getting a dark mass, with no details, so stick to light coloured options. For low key, it doesn’t matter as much, but darker colours come out better as far as I’m concerned.

Ever had major problems with what your subject was wearing, or don’t you even think about it?
