I think I screwed up with some of the wedding planning and I'm worried I may have offended my future SIL. About a month or so ago, we learned that my SIL is expecting her second child. I'm beyond happy for her. The only slightly rough spot I saw was going to be finding a dress that would be comfortable for her. At first, I thought we'd all wear satin, but after learning about her pregnancy and realizing that satin would be rather warm, I told everyone we should go with chiffon. Well, after going to a bridal store and 2 of the girls trying on things, they decided they liked a charmeuse one. The other one tried on the charmeuse dress later and said she liked that one too. I completely forgot to email my SIL to tell her about the change. When I remembered to this weekend, she didn't pick up and bought a chiffon one. When I finally talked to her today and she told me she bought the chiffon one, I told her the chiffon was fine with me and offered to buy her another dress if she wanted to change dresses. She said she was fine with that one, but I still repeated my offer.

I also invited her to a very impromptu get-together with the other bridesmaids on Wednesday. A couple of weeks ago, my best friend and I talked about getting together while she was visiting her MIL this week and we decided to on Wednesday evening. Yesterday, the 2 bridesmaids that live in town said they could come. So I extended the invitation to my SIL and told her if she couldn't come, it was completely understandable because of how last minute this was and that her daughter's birthday was a couple of days later. Maybe it was because I was still in freak-out mode, but she sounded upset about this as well.

What can I do to fix this? I don't want to start the next chapter of my life with my SIL angry or annoyed with me. I've been racking my brain for other things I can do, but I'm coming up empty. Any thoughts? Thanks for reading a long and whiney sounding post.
