Single-breasted vs. Double-breasted: Single-breasted suits are versatile and widely worn, featuring a single column of buttons. Double-breasted suits have two parallel columns of buttons and offer a more formal, traditional look. Slim Fit: Modern and stylish, slim-fit suits contour closely to the body. Ideal for a contemporary look. Wool: The most common and versatile fabric for suits, suitable for year-round wear. Cotton: Lightweight and breathable, great for casual or summer suits. Linen: Perfect for hot weather, but prone to wrinkling. Blends: Wool blends, often with polyester, offer durability and wrinkle resistance.
