Well, my shopping trip last night wtih 3 of my BMs went well, thankfully. We went to DB and weren't sure if we would find something, but we did. At first, each of them had found a style they liked, and they were all different. But then we saw another in a photo, decided to try it on, and turned out they all looked awesome in it! I didn't care either way if they had different styles or not but it worked out to be that they all have the same one. I'm super excited, it's amazingly flattering on all of them and they all have such different body types.
We are getting this style, in this color shown, called "pewter grey":
Now we just have to send the info to my BM in California so in the next month or so she can go get sized at a DB there.
