Welcome from both a fellow Texan and a Wilson.

Footwear is a person issue... You could wear anything from ghillie brogues to sandals, depending on your manner of dress. Shirts, either a button up or polo's look good, but, again, it's a personal preference. Now colors, I have my preferences... I like loden, lovat, and bottle greens...some navy blues, grey, and khaki. I would say, check out the photo galleries, look at the photo galleries of the vendors, and see what other people are wearing, and develop your own style, based on your own taste.. Basically, you have to be satisfied with your look, before you even worry about what anyone else thinks.
