That's a good point EWQ. Besides that, the mind works in a weird way. If you decide work at home for a day and you slip into your work gear, your mind adjusts into work mode.
Anyway, I just wear dress pants and a nice dress shirt, with a nice pair of black shoes. No ties or anything. We only get the high ranked people of other companies at our company, and it appears they like to see a tech support department dressed up nicely instead of in worn out jeans. I guess it all depends on the industry.
Still, put me in a suit and I've noticed to get much more female attention, even if I'm overweight
Problem is, I don't have a fitting suit anymore
