I want to thank everyone who has answered so far and hope you will all indulge me with more responses.
There really is a method to my madness. I am considerably overweight. To camouflage that asmuch as possible these are the guidelines I go by:
Wear darksolid colors - avoid light colors and patterns (stripes OK in moderation though don't look good with suspenders )
Wear long sleeves - avoid short sleeves (not always easy in the heat)
Wear long pants - avoid shorts
Wear pants at natural waist - not at hips
Wear suspenders instead of a belt
Wear a dark sportscoat or suit as much as possible - 2 button, single breasted, tailored - with top button buttoned
Light colored shirts (white, light blue, pink) are fine when I will be wearing a dark jacket, buttoned, over them. However, I live in Texas and work in Saudi Arabia, so much of the year jackets are out of the question. If I want to wear a solid dark color above the waist during these times, it will be a long sleeve, button up, collared shirt of some kind. I could always wear French blue, but that gets a bit monotonous. I look good in maroon/burgundy and it coordinates well with khaki, blue (navy or dark denim), or mid- to charcoal gray pants. I'm open to suggestions on other available dark shirt colors that will coordinate with these 3 pants colors.
If I were 50 pounds lighter, I would wear light blue, white, pink, plaid, stripes, etc. all the time. However, if I did now I might be mistaken for the Goodyear blimp.
I looked at the micro checked shirts. Its small enough that it gives the impression of being solid but the white in the check makes the base color look very light (a lot like a black and white shepperds check tie looks gray).
