Hang suits and sport coats on a wide wooden hanger and let them rest a day between wears. Brush, don't wash; dry clean only when actually dirty — two or three times a year is plenty. Steam out creases. Hems, sleeves and waists are done in our shop at 6 N Centre St; add your inseam in the order notes and we'll hem trousers before they ship. Hemmed trousers are altered to your order, so they can't be returned for change of mind or wrong size.
