Thanks for the info. This is not an easy task for me. I can't stand shopping (unless it's for books or music).
The colors for the wedding are navy blue and peach. So I have to stay away from them. My sister is wearing a peach dress, and don't know what she'll wear for the other two events. I know she has outfits in her closet. I don't. The closest dressy thing I own is my concert attire, long black skirt and black blouse. Totally inappropriate for a wedding.
A long dress in rose, turquoise or lavender would be good because I look good in those colors. I could probably get by with a pants suit for the rehearsal dinner, provided it's dressy enough. I'm going to have to tie up my sister to find out about the luncheon.
The major problem is the size. I wear a 16, and many times have to go up into the Women's sizes. Trust me, because I've looked, clothes in the Women's sections are about as stylish as a burlap sack. I don't like to order online because there's no guarantee that the clothes will fit, and many places do not have a return-free policy. Not every company is as accommodating as LL Bean and Land's End.
I'm probably going to have to go to either Alabama or Louisiana to find something suitable. We don't have many shops here that would have what I'm looking for.
Jewelry will be the easiest. I have some lovely pieces, both of my own and what I inherited from my mother.
