Re: WHAT NEXT?????
^ You should ask the beauty parlour how long they will take. Tell then what time you need to be ready by and they should be able to advise you at what time to arrive.
For my cousin's wedding his wife went to the parlour at 4pm and was ready by around 7pm. The photo shoot was done straight afterwards at the parlour. She had photos by herself then my cousin came around 7:30 for them to have photos together.
