All of our dresses are created to your custom measurements. We require 30+ measurements along with specific measurements required for your unique design. Over time, we have developed our custom measurement guideline that is easy to use, and all of our past clients have been able to find a local seamstress or tailor in their area to measure them for their custom wedding dress using our guideline. We provide all information for you, and are here for you if there are any questions. Alterations will be up to the bride/client. If the measurements are done correctly, and the client does not go through any weight changes, the dress would only need very little to no alterations since the dress is made to your custom measurements.
