The number of fittings will depend on the Dress Option that you go for.
A Custom Unique dress will require 5 fittings.
A Customised Read-to-wear gown will require 2 fittings.
A Ready-to-wear gown doesn't require a fitting at all, you just come in to try and buy.
When you come to your fitting, you need to bring the undergarments that you will be wearing on the day, shoes, jewellery and anything thing else that will form part of your bridal attire. This will ensure that the length, bodice and any other considerations are made to fit perfectly.
