A polo shirt is a very adaptable piece of apparel. A polo shirt is the ideal combination of casual and dressy. It's more formal than a tee and less formal than a dress shirt. Your best bet is to look for a polo shirt that has some sort of pattern or design on it. These can range from a simple plaid to a more intricate print. In general, men should avoid wearing a polo shirt with a button-down collar and sleeves. This looks too formal. Instead, go for a polo shirt with a relaxed fit and open collars. They will still be comfortable but not as stiff as a regular shirt. Polos are easy to wear and easy to take off. You can wear them to work or play. So if you're looking for an outfit that's comfortable but also attractive, then consider adding a polo to your wardrobe.
