You should book your appointment as soon as possible. For a groom setting up his event and choosing a style, 3 - 5 months before your event date will ensure that you and your party have enough time to check out. For participants (people in an event with a look selected for them), 1 - 3 months will allow you to get your sizes and check out without having rush fees.
In general, if you're going to visit a showroom for a fitting, we strongly recommend you do so no later than a month prior to your event. We can assist you up to five business days before your event date. Please note we start charging rush order fees 13 days before an event date.
