Hamilton Shirts

Off-the-rack clothes never fit perfectly, but the recent surge in custom online options means guys can get made-to-measure without even leaving the house. Leading the way is Hamilton Shirts, the century-old Houston purveyor of Western-style shirts. Its website offers thousands of custom combinations: sizes, fits, fabrics, collars, cuffs, and style. Start with a basic white shirt that fits beautifully, tucked in or not, then experiment with colors and patterns. Also worth checking out: J. Hilburn's custom clothing service and Proper Cloth, which helps shoppers design as well as fit new shirts. [From $245; hamiltonshirts.com]
