Different players have different ideas and motivations for what to wear at the poker table. Some insist on dressing for confidence, some for comfort and others have a specific image that they want to project.
For me my choice of wear at the table intersects between all three of these areas. I am a middle aged male and I am happy to appear as such so I’m not attempting to style myself as a young man anymore. My look should tell you that I have been around for a while, traveled some, seen a lot and understand the game that we’re playing.
A collared shirt and dress pants make me feel most confident however this significantly reduces my comfort level. When I’m at a table for 5, 6 or 12 hours I just can’t stand this type of wear. I’ll generally opt for straight leg jeans, dress shoes and a neat t-shirt. My wrist is usually adorned with a nice watch or a conservatively styled bracelet (no “bling” for me). In this outfit I can sit for as many hours in complete comfort and not draw more attention to myself than I desire. I will also have a hooded top at the ready which I usually don’t require but some poker rooms are inexplicably hot or cold so I think it’s best to be prepared.
My advice is to find a few pieces that feel the best on you at the table and rotate through them at your games, try out different styles and you’ll find your personal niche.
