I went to Davids Bridal in Bowie and picked out BM dresses 4 yrs ago. Didn't have any problems at all. I didn't need a gown because I borrowed my sister in laws.
Not sure if she still does this but she works from her home and she did/does alterations for the dry cleaner I use to work for years ago.. Never had any complaints:
They didn't close. They moved to a new shop in Edgewater. I am getting married in 3 weeks and got my dress there. They are AWESOME! The owner (Dora) goes out of her way to be helpful without being pushy (it was the only place I went where they didn't insist on sticking a veil on my head) and the seamstress went out of her way to make sure my mother was happy and that I was happy.
