Are you supposed to "hire" a seamstress to alter the BM dresses and wedding dresses? My wedding is 10/20/12 and i just got the call today that my BM dresses came in. When I was a BM at one of my friends weddings she had a lady there like 2 nights before her big day and she measured us all and just did the alterations at her house. Is that normal? What are other options? TIA
