Sorry if this sounds like a rather odd question, but what should one wear when photographing in the following situations,

Parties - outdoors and indoors
outdoor fashion shoots
Children in school / nursery setting

Obviously one wants to blend in and not look too out of place. I also need to relax the subjects as much as possible so that I get natural looking shots.

On the other hand I want to wear something that is comforatable to move around to get well composed shots.

I was at a wedding recently where I was a guest and found that what I was earing prevented me from taking many shots I would have liked. It can be a bit awkward to get shots form teh ground loooking up when wearing a suit, for example!

I am just a beginner here and would welcome any advice and guidance from those with more expereince.

Many thanks
