One of Duckie's best friends will be celebrating her Bat Mitzvah in June and Duckie will be invited to the ceremony in the morning and the reception in the evening. The girl's family is not Orthodox, but rather Conservative. Her friend advised me that Duckie's dress for the ceremony at temple should be modest with at least cap sleeves, a respectable neckline and at least knee length. She can wear a dress suitable for a wedding reception for the evening. I have been looking online for places to shop for the ceremony dress but it looks like everything is sleeveless or too short. Duckie does not want to wear a sweater over a sleeveless dress because it will probably be very warm that day. Does anyone know of a national chain that would sell something appropriate?
