[Theisey]

Uniform worn by Track/Field officials will depend on where you will be assigned meets and the association you belong too.

Pretty much the standard for outdoors is khaki pants/shorts and white polo possibly with an assocation logo along with a some kind of (optional) hat.
There are many other variations, such as for indoor meets where the uniform might be grey or black pants w/white polo or be grey pants with white shirt w/tie and a blue blazer.
invitationl meets sometimes supply shirts and they can be of many colors.

USATF meets have what they call a "National" shirt.

Bottom line is join an officials association and they'll tell you what the proper uniform is.
