The composition and construction of a suit is the foundation of the garment. Like making a car with a poor quality engine, cracks will appear when it comes down to business, no matter how slick it looks.
Modern day suits come in a wide variety of fabrics from polyester to wool, cotton to linen, rayon to silk as well as combinations of these variants in different proportions. Additionally, materials like elastane, serona and nano-fiber technologies have also been incorporated in small quantaties into suits in order to provide added flexibility or stain resistant characteristics.
The components that make up a suit are equally as important. The canvas which provides the jacket structure, the lining which allows for comfort and feel, the shoulder padding that shapes to the wearer, the stitching that provides strength to the fabric and the waistband are there to bear the strain of movement. All these parts make up the composition of the suit and need to work in unison.
It is important to understand that there will be trade-offs when it comes to budget and quality but investing in a high-grade fabric will reap rewards when it comes to longevity of your suit.
