Polo is an outdoor sport, so dress according to the weather. You really can’t be over or under dressed. Spectators at a polo match wear everything from jeans to high fashion. If the polo match you’re attending is a major tournament, charity benefit match or special event, you may want to dress up. If you want to go divot stomping at halftime, and you should, it’s a good idea to wear shoes for health reasons and a hat for sun protection. Other than that, be comfortable. Polo clubs allow spectators to bring food and drinks. So pack a picnic lunch of items that will travel well for an afternoon sporting event.
