My dress for my brother's wedding

I'd go with the back-up dress just to be on the safe side! I'm assuming yall will be in family pictures together, and she may not appreciate someone else wearing white in her pictures as well. It depends on how much white is in the dress, though.... if it's mostly white with smaller flowers, I'd say to steer away from it. I wouldn't really like a close family member wearing a white dress even if it did have some other colors in it.

Can you post a picture of the dress?

I would definitely go with the backup dress. If you have to wonder, it's best not to wear it. White is the one color wedding guests should actively avoid (and I suppose any super light pastel) and I think it comes across really rudely when someone chooses to push that boundary when they could've gotten another dress color altogether.

This is not a big deal. It clearly is not a wedding dress.

I'd go with the backup dress. I think the safest bet is wearing something with no white at all.

Should be fine. However if you question it then you should just do the back up one

I had the same concern for my FSIL’s wedding last May. FH loved the dress on me and didn’t seem to understand my concerns 🙄 my sister who is wonderful knew how stressed I was about it and ended up ordering and rush shipping a royal blue dress for me which I ended up wearing. I wore the other one to the rehearsal dinner since she was wearing blush. I say if it concerns you, then go with the backup.

The only person who can actually answer if the dress will upset you future SIL *is* your future SIL. We can tell you if *we* don’t care, but we’re not her. The best thing to do is text her a pic to clear it ...id send pic and say “this isn’t too much white for the wedding is it? I love it but I have a back up just in case!”
if you don’t have a texting relationship with her, ask through your brother, same-ish text just add “hey, can you ask Xx if this is okay? —

Definitely the backup dress.

I don’t think this would be a big deal if it was a random guest but since you’ll be in family photos I’d definitely use the backup

I think backup dress just to be safe! You're very considerate

Thanks everyone!

Just my 2 cents, I wore a white shirt (thinking it would look awesome with this red-orange statement necklace I got) to my friend’s bachelorette party 3 years ago and still feel bad about it to this day. I felt a little ridiculous and you can tell in the pictures of that day. I know its totally different situation here, but my thought is better safe than sorry....

Ask your future sister in law. She's the only one who can tell you if she'd be upset or not. Lots of people have different views on the subject. Some people think it's no big deal to wear white at all while others think it's the biggest insult you could throw at a bride. Send her a picture and say is this ok or would you rather me wear another dress?

I have returned from my brother's wedding and it was not an issue.
