Bridal boutiques carry gowns of all sizes and offer alteration services, so purchasing a gown in a bridal shop is the simplest option. Another possibility is to purchase an used gown through a site such as eBay and employ a tailor to alter the dress upon arrival.
When altering a woman's dress to fit a man, it's important to consider body shape differences, such as waist placement, for a woman's waist is above the belly button, instead of below. To ensure a proper fit, wear the same foundation garments for the big day on every fitting. Another way to find the perfect gown is to enlist the services of a professional tailor or seamstress to help design and craft it.
