My mom is almost 60 and I have printed out about 80 dresses because she is going to buy it when she comes to my city. I found them on this website, modernbride under dressfinder; mothers. There are all different styles. I checked out dresses at the bride botiques and I think those are the best options because they are actually made for mothers. I would like my mom to wear like a 3/4 length dress, plain, straight, with a blazer style jacket on top, she can take it off after the ceremony. It is hard to describe, but there is also a section on REAL MOTHERS, which can give you some good ideas too!
