The best fabric for a shirt depends on the occasion and desired style. Cotton is a versatile choice, offering breathability and comfort, making it perfect for both workwear and casual wear. Silk or satin are great options for a more refined, luxurious feel, ideal for evenings or special events. Linen provides a cool, breathable option for warm weather, offering a laid-back vibe, while a cotton-polyester blend is durable and low-maintenance. Consider your personal style and the event at hand when selecting the fabric, along with colours that suit your wardrobe.
