There will be at least one fitting. At this appointment alterations will be pinned into position, you will be talked through what needs to be done and given your official quote if you haven't already had it.
After this the dress may be finished off permanently ready for collection, or for more complex alterations, a second fitting may be required.
Payment needs to be made before the collection date.
You will absolutely need to remember to bring along the shoes that you'll be wearing with the dress.
Bridesmaid / prom/ evening dress fittings can take anywhere between 20 mins - 1 hour, dependant on what you actually need doing.
