light blue, off white, or teal shirt
No.
a grey shirt or a gray pants.
White or Grey.
Any color shirt really, anything matches gray.
Black, white, a darker or lighter shade of grey,
White\grey\black plain shirt(:
Grey
Depends on what you are matching it with. What color is your suit/pants? Get that color on your tie and you should be OK. Medium grey (in a glen plaid) or tan could work.
Grey, or black
yes, why wouldn't you be able to?
Gray pants will go well with any color. I would chose something depending on the season and the event you are attending. Bright for summer and spring,
pink, grey color shirt will be good. White shirt and Black pant will be good.
