I always prefer doing the trial as close to the wedding as possible. 1- 2 weeks before the wedding is best.
I do my most trials Wednesday mornings between 09h00 and 12h00. These are the times my busy little monkey toddler is at school and we can have a quiet, serene environment in which to be creative.
I suggest you book your trial before a dress fitting as you will then be able to see the hair and makeup look with your dress.
As mentioned above 1 – 2 weeks before the wedding works well as it gives you time to give me feedback as well as keep your look fresh in my memory.
Booking the trial is the responsibility of the bride.
