Clothing color doesn't matter so much, mainly just style. Don't wear torn t-shirts and overalls, those are definitely not my favorite. As for shoes, depends what type of shoes. As long as they're not some weird boot heel pink thing (etc.), you should be fine :)
the color of the clothing does not matter. what matters most is 1)cleanliness (like Anon said, no tears, but make sure it's also washed and doesn't have any stains) 2)the fit 3)the style (this is subjective to each female's taste)
As far as shoes go, it's the same thing but I would take it a step further and say that you should also try to match them with your outfit
As far as colors go, anything. I like simple shirts though, if you can stick to one color, great. Blues, blacks, and whites are a personal favorite. But choose a color that YOU like so it reflects who YOU are. I have a friend who wears neon orange all the time because he says its who he is. He still gets dates. :)
Shoes, just nothing to obscene. Pick your shoes according to the occasion. :)
According to science red is supposed to be the sexiest color to wear, however, every girl that I've talked to has agreed that blue looks better on men. As far as shoes go I think black looks very mature. =)
I personally like plain and dark shirt... black or navy blue... the shoes should go with the shirt, no brown shoes with a black shirt... and if your wearing a nice button up shirt or something, wear dressier shoes that go with, no gym shoes or sandals with nice shirts!
