She’s asked to wear a restrictive outfit in sweltering heat, but her pregnancy makes it an impossible task.

I, 25f, am having a conflict with my husband’s sister, 36f. She is getting married in 2 weeks, and her dress code is incredibly complicated to adhere to for me.
It is black tie, long sleeves, and floor-length gowns. The conflict happened because I am currently 34 weeks pregnant and overheat very quickly, and the wedding is entirely outside, in the middle of the day, in the southern USA where it is incredibly hot.
I cannot be in a long-sleeve, floor-length gown in the heat for 8 hours.
I have sent her a few dresses to try to compromise, which I will link in the comments for further information, but she is completely adamant about exactly what she wants.
I told her yesterday that I cannot attend her wedding if she is not going to budge even slightly on the dress code. I told her she has the right to have her wedding exactly how she wants it, for it to be her perfect day, but I have the right to look out for my own health.
She freaked out at me and told me I was being incredibly selfish and that “for once it isn’t about me and my fucking baby,” which she only said because she’s jealous I’m having the first grandchild and she felt like she should have had a baby before me and my husband.
Since then, my husband’s side of the family has told me I’m being selfish and to just compromise one day to keep the peace. I don’t think I should need to compromise my health for her wedding.
Am I the asshole and being unreasonable?
Conclusion
Will she be forced to choose between her health and attending the wedding?
The family’s reaction adds another layer of drama, leaving everyone wondering if this wedding will even happen.
Here’s how people reacted:
Ok, don’t tell her that (although it’s true). Just don’t go. And have your husband deal with his sister. It’s HIS job to deal with his family and HIS job to look after his very pregnant wife.
You’re NTA regardless but black tie before dusk is wrong, and it’s wildly inappropriate to demand full length gowns outdoors where hems will drag on dirt, grass and whatever else is on the ground.
NTA, OP. Not even a little bit.
When she uttered *those* words, you received a reprieve from the wedding regardless of what anyone else is spewing. I think some people need to learn the actual definition of the word. She is focusing on her ‘vision’, you, on the other hand are focusing on the health of your unborn child.
Selfish: concerned excessively or exclusively with oneself : seeking or concentrating on one’s own advantage, pleasure, or well-being without regard for others
: arising from concern with one’s own welfare or advantage in disregard of others.
Unless this woman also happens to be an obstetrician, and can offer sound medical evidence your baby will suffer no harm, and is willing to have a neonatologist on standby, you are fully within your rights to take a pass on what will undoubtedly be a very unpleasant day for everyone.
Your health and the health of your baby are of the utmost importance and certainly more important than any ‘aesthetics’ the bride is imposing on guests.
There are going to be a lot of uncomfortable and unhappy guests at her wedding. I truly hope no medical emergencies arise, as that too would ruin the ‘aesthetics’!
NTA, mamma. I truly hope your husband is siding with you.
Wishing you a safe and easy delivery!
It’s medically unsafe for you and your baby
And it’s tacky for a mid day affair.
Is the bride really going to want to compete with a fainting pregnant lady? Cuz that’s what gonna happen.
Bride gets to decide what her bridesmaids wear, not the guests. “Black tie” is a dress code. The rest is her not understanding how weddings work.
You’ve gone above and beyond trying to accommodate her delusions. You’ve stepped aside very politely since a compromise can’t be made.
I can’t imagine anyone handling this with more class than you have. Enjoy not being on your feet for hours in 100+ degrees. Congratulations on your baby!
YOU are NTA. SHE is going to have a LOT of fainting guests.
