Yes if you can! Men generally wear starched jeans, a pressed shirt, a jacket/blazer, a felt cowboy hat, and cowboy boots. Women can wear anything, but in general we suggest a knee to ankle length semi-formal dress (for suggestions, see: IG > Little White Looks > Western/Mountain). Cowboy hats and boots are optional for women. Also bring a jacket or a wrap to account for the unpredictable Texas weather.
