Buying is generally recommended for the groom to ensure a perfect fit for photographs. Rental suits often have boxy fits and limited alteration options. A custom-made suit is an investment that can be worn again for work, the races, or other weddings. If budget is a concern for groomsmen, many parties choose to have the groom in a custom bespoke suit while groomsmen wear high-quality ready-to-wear or rental options that are color-coordinated.
