For one sister In law to be the bridesmaid and not the other?

I'm unsure if I'm being over sensitive but I've been stewing on this since a family bbq on Sunday.

My sister in law got engaged christmas day. She is younger sister of my husband by 18 months. There is also my husbands twin brother and his wife.

We are all a similar age. Moderately close family. We see each other maybe once every 6-8 weeks.

At the BBQ on Sunday there was wedding talk. It emerged that my sister in law is going to be a bridesmaid and I'm playing no part in the wedding.

I knew DH's sister and our sister in law got on well but i didnt know they were this close. I have a nice relationship with them both but I hadn't expected to be a bridesmaid. However, I feel really hurt that she would ask one of us and not the other.

Am I being unreasonable?

That is a bit off to be honest. Fair enough if the other SIL wasn't married and you were or if she was younger or if you had kids and she didn't. But when everything is fairly equal then you should be treated the same.

I was also wondering whether you will actually get a role - looking after any children attending.

MissBridgetJones · 13/05/2025 13:43

Yes, you are being unreasonable.

It is the type of stunt I have heard of years ago tried on a friend by her MIL, via her husband, when one sister in law was married with toddlers and being MOH to another sister.

She told her husband and MIL that she'd rather give it all a miss so.
Her children were 8-10 znd she wasn't doing toddler care for anyone.
She was very irritated at the suggestion and made it known too.
They paid a babysitter at the hotel for the day as in laws were also invited and refused to do it.

At first glance it looks unfair for there to be two family members of the same status (SILs) and invite one to be BM and not the other. But if you reframe it as which of the the bride's friends should make the cut, the other SIL probably qualifies as a close friend and you are less close friend/ family member. It might help to think of it like that.

This is probably irrelevant since you hoped to be asked but I would have felt a total wally as a bridesmaid over 40! I would probably say yes if asked, out of politeness, but i tend to see it as a role for children and young adults.
Sorry if I missed it but do your children have a role in the wedding?

Mashbutterfly · 13/05/2025 13:59

Thank you all.

It isn't that I'm dying to flutter about in a bridesmaid dress. Just that it made me sad to think I'm a bit less well regarded. I knew occasionally they did things with them and their partners and kids, but assumed it was just because their kids are closer in age.

In answer, all 3 of us have children. Mine are 4&5, SIL getting married has two aged 9&11 from previous relationship & bridesmaid sister in law has an 7 year old & 10 year old.

Brides children are flower girl and mini usher but no other kids in the wedding party.

This is exactly it. I'm over 40, I'm certainly not a teenager sulking in the corner. It just stuck me as an unusual thing to openly say "I get on better with that one than that one"

I just feel a bit sad to think that me and my kids are a bit more excluded from the family.

I suppose the crux is that I wouldn't have done it myself.

But she hasn’t openly said that. She has openly said “I have chosen SIL(1) as my bridesmaid.”

The rest are words you’re putting in her mouth based on your own feelings about being SIL(2) and “only” a guest.

No doubt she either only wanted 1 or already had one or two people to ask, but wanted representation from her DH’s side. She doesn’t want or need even more bridesmaids. You don’t know what they might ask you to do to be a part of it, but you’ve openly said you aren’t close. I wouldn’t expect to be anyones bridesmaid I wasn’t particularly close with.

JoshLymanSwagger · 13/05/2025 14:08

@Mashbutterfly Assuming the kids are invited, you'll have your hands full with your own 2. At least they won't have to fling petals around. Grin
If they're not invited, can you get overnight childcare and let your hair down.🥂💃🏻

A 4 and 5yo will need full on watching over while a 7yo and 10yo is very much independent. I think that would play a factor, as well as that they are friends outside of the family.

IamnotSethRogan · 13/05/2025 14:49

One of my sister in laws and I are best friends. I get on well with the others and like them fine but i am extremely close to this particular one. I was also her bridesmaid.

I wouldn't over think it. It's nothing personal against you.

It’s completely natural to feel hurt when you're not chosen to be a bridesmaid, especially when other SIL is. That kind of disappointment can sting. But you're not alone—and there are definitely some downsides to being a bridesmaid, particularly in the UK where wedding culture has its own quirks. Here are three of the top ones:

  1. It’s Expensive (and often awkward to discuss)
Being a bridesmaid in the UK can cost hundreds—if not over a grand—once you factor in:
  • Hen do (often a full weekend abroad these days!)
  • Dress, shoes, accessories (which you often have to pay for)
  • Hair and makeup (sometimes not covered)
  • Travel, accommodation, and gifts
And unlike in some countries, there's often less transparency or discussion about who's paying for what, which can lead to pressure, guilt, or awkward situations.
  1. Heavy Time Commitment and Emotional Labour
You’re expected to show up for planning meetings, fittings, the hen do, possibly help with any DIY wedding prep, and be emotionally available to the bride—even if you're going through your own stuff. This emotional labour isn’t often acknowledged, and it can be exhausting, especially if you’re juggling work, a social life, or your own challenges.
  1. You Lose Autonomy on the Day
Bridesmaids don’t really get to just enjoy the day like a regular guest. You’re on a schedule, often wearing something you didn’t choose, managing logistics, and making sure everything runs smoothly. There's pressure to “perform” joy and be helpful—even if your feet hurt, you’re starving, or you’re dealing with personal feelings.

Letting go of the story that this is about your importance or lack of importance can free you from feeling rejected. You can be an incredible SIL without wearing a matching dress.

Her wedding, her choice. I have 2 sisters & 1 brother. I only had 1 of my sisters as a bridesmaid, alongside some friends. It wasn't to spite my other sister.

LadyQuackBeth · 13/05/2025 15:45

Did you have her as a bridesmaid? Did the other SIL?

It could even be something as simple as SIL once saying "I've never been a bridesmaid." I'm pretty sure it's not about you, don't let it affect your relationship.

Communitywebbing · 13/05/2025 15:45

Don’t go there OP. Be pleased you have some pleasant family relationships. Lots of people don’t and many long-standing resentments start at weddings.

Mulledjuice · 13/05/2025 15:50

Given your update I assume your children are invited and it's assumed (given their ages) that it's assumed you'll ne looking after them.

Sassybooklover · 13/05/2025 15:54

I have 3 sister-in-law's (2 are my husband's sisters and the other is my husband's brother's wife). I asked none of them to bridesmaids, simply because I didn't want to ask 1 without the others. I'm pretty sure 1 would have said no, she's not at all girlie, and hates dressing up. I don't have siblings, so asked 2 friends. My husband's brother was best man and his 2 sister's were witnesses. My husband's sisters then husband wasn't given a role and neither was my husband's brother's wife either. I do understand why you'd feel hurt. However, look upon it, as in you can enjoy the day, without any pressure or role to perform. I don't think it's a reflection on you, it may be that she's closer to your other SIL.

CraftandGlamour · 13/05/2025 16:10

"But when everything is fairly equal then you should be treated the same"

But why? I'm sorry I dont agree. Are these women actually children? YABU. As others have said you don't get to be BM just because you're related. Yes, it can be disappointing to realise you're not liked as much as the other SIL but you've said yourself you're not that close. I think this really comes down to you feeling sad because your ego's had a knock. That's okay. Just don't let it spoil their day. Or your enjoyment of it.

OhGodImBloated · 13/05/2025 16:16

I get why you’re miffed. Not only was I the only ‘close’ relative not involved in BIL & Sils wedding party, but I was the only relative not involved in a specific thing up at the front on the day too. Every other person from the family pews including my toddler and DH was up at the front except me. I felt such a lemon. The bride and groom later said that was an oversight on their part but we had a rehearsal the day before and I was present for that too - same thing happened.

Later when they showed off the wedding album, I wasn’t in that either even though there were loads of pics and all other family members were included in various groupings! However, I know genuinely there wasnt any ill will involved, just a bit of oversight. We were fairly close back then and still are so this had no bearing on our relationship.

Ultimately, it’s one day and then everyone else forgets the detail of it. I am much more sensitive than SIL and except for marrying brothers we have little naturally in common but I value family and we put effort into our friendship. I know I could rely on her if the chips were down.

Nobody noticed or commented that I was “excluded” during the ceremony, everyone was just enjoying the day and I think you’ll probably find the same thing. Just show loads of support and happiness even if you have to fake it til you make it. If you feel inclined, volunteer to help with something (favours or hen do planning?) so that you feel part of it more than a guest, but otherwise just enjoy the day with your kids.

Youstolemygoddamnhouse · 13/05/2025 19:24

It’s her wedding. She can do what she’s like. Was she your bridesmaid or involved in your wedding?

AmIHumanOrAmIAYeti · 13/05/2025 19:25

My BIL and SIL eloped and didn’t even invite siblings to their wedding!
