What looks nice? Casual wear consists of nice jeans (no holes or frayed hems) and a nice shirt with a collar. If sneakers (tennis shoes) are worn, they should be white and not scuffed. Another casual look that goes over well here in my area is jeans and a long sleeved cotton western shirt that has been starched, ironed, and a nice pair of boots. A cowboy hat is very optional, depending on the occasion, but can help to make a man more distinctive and a cut above the rest of the dime store cowboys. For dress wear, you just can't find fault with a many who wears a suit, freshly polished shoes, a starched and ironed dress shirt and a tie. I am admittedly a old lady, but I do not care for the style of dressing where the man wears a polo shirt with a suit. Go one way or the other. If the occasion calls for a suit, do it properly. It does not take a lot of money to be neat and clean and well pressed. That trumps a new suit with a wrinkled shirt and scuffed shoes any day of the week.
Day clothing- dress pants and shirt.
Jeans and t-shirts are a little tastless
Clean shirt, ftted pants and comfortable shoes. Shoes are the top 1 element for me. Sneakers and dress shoes are just fine. Socks to match shoes are also important. Black socks with dress shoes and white with sneakers. Good-quality colored socks make you different from simple looking. If you've never get involved with colored socks, funny socks retailers, such as Happy Socks, Fool's Day Funny Socks are good choices.
