The woman at Daniela's GB is beautiful (assuming she's still there). Mum got gorgeous dresses for both mine and my brother's weddings there. Because the lady knew mum was looking for something special, if something new came in she'd hold it and phone mum. So nice dresses for all ages and styles. Unik is nice too and they have Spurling there as well - but I don't know if it's just hire or whether you can buy.

ETA - My bridesmaids dresses were bought from Ferrari formal wear in Heidelberg. They had beautiful dresses, although I remember we weren't that impressed by the service at the time.
