Camp collar shirts, also known as Cuban collar or revere collar shirts, feature a relaxed collar style that adds a touch of retro charm to your summer wardrobe. These shirts often come in lightweight fabrics like cotton or rayon and are available in a variety of vibrant colors and playful prints. 

Fit: Opt for a relaxed and slightly oversized fit for a laid-back vibe that's perfect for summer. However, make sure the shirt still fits well in the shoulders to maintain a polished look.
