éOur signature modern two button flat front suit combines the best features of classic-fit and slim-fit designs to give you comfort and utmost style.Size 42 and below are in what we call a perfect slim/classic fit. Size 44 and above are in classic/regular fit.Made from 100% SuitTech, our signature poly fabric is built similarly to that used in comfortable high-performance athletic wear. It is moisture-wicking, breathable, light-weight, anti-deforming, anti-bacterial, form-fitting, and allows the suit to be machine-washable in cold water and can be tumble-dried at low heat. Just turn the jacket inside out when drying. No dry cleaning needed! (As a precautionary step there is a dry clean only label on some of our SuitTech suits, but it is not required.)Our suits are sold in sets, we are unable to mix and match sizes for any order. If the sizes listed do not match what you need, please note that always go with the jacket size that fits you well and have the pants tailor if needed. Our pants have an extra 2" of fabric in the waist and 1/2" in the inseam that could be let out by your local tailor; up to 3" in the waist could be taken in. Since all of our pants come unfinished at 36" long, when you take the pants to your tailor to get them hemmed, the tailor can adjust the waist to fit you.
