DSIL has asked me to wear a non matching outfit on Christmas Day

I am friendly with DSIL and we get along well. She text me earlier to ask what outfit I’ve planned for Christmas Day (as we are all at MIL’s house this year).

It turns out we’ve planned something very similar, near identical infact.

She has suggested I wear something else so we aren’t matching.

I purchased the outfit specifically for the day so am reluctant to. She has already travelled down to MIL’s (she lives 3 hours from her) so doesn’t have an alternative.

Am I unreasonable to stick to what I plan to wear? It’s not as if we are going out on the day.

Is she worried about how it will look on her Insta?

Just wear something else so you don't look silly by twinning with her.

Why is it silly? Christmas clothes are likely some variation on red, gold or sparkly so it's hardly surprising if there's similar. I don't get why it's a problem.

Wear what you want, it really doesn't matter. It's not a wedding, it's the family Christmas dinner.

PluckyChancer · 23/12/2025 17:59

She’s being ridiculous. You can wear whatever you like as it’s not the exact same outfit anyway, just similar.

I’d be quite firm and tell her that you really like what you bought so having thought about it, you’ve decided to wear it anyway. Let her think you gave her stupid suggestion some consideration.

Honestly, what sort of person cares enough about such mundane issues? 😳

APatternGrammar · 23/12/2025 17:59

Tell her you don’t have an alternative. Offer to bring her a scarf or a cardigan to borrow to make it look a bit more different from yours. If she cares that much presumably she can switch her Christmas day and boxing day clothes.

LittleBitofBread · 23/12/2025 18:00

Christ, who cares. Before I saw the whole post I thought you were going to say she asked you to wear a non-white outfit to her wedding or something, which I could understand, but Christmas Day with family? She needs a life/better things to worry about.

MeNotMyselfAndI · 23/12/2025 18:01

Batshit 😂. I can’t begin to imagine asking this, answering it or doing anything other than laugh if I turned up in the same outfit as someone 😂

Reachingforthesun · 23/12/2025 18:01

Text her something like "Oh that's so funny Janet, great minds and all that! We'll both look fab😉 "

Your DSIL is being ridiculous.

Didimum · 23/12/2025 18:01

I’m struggling to see why it matters being matching. It’s just Christmas Day.

Anonanonay · 23/12/2025 18:03

Yabu for buying clothes specifically for Christmas day, let alone comparing outfits.

Purplecatshopaholic · 23/12/2025 18:04

I take it if you are not going out she’s putting the pics on Insta? Barking either way, wear what you like!

AgnesMcDoo · 23/12/2025 18:04

Wear what you want. She’s being an idiot.

TheMotherSide · 23/12/2025 18:04

Is it your brother's wife or your BiL's wife? Not that ot really matters -it's still nuts, but I suppose the former is a bit closer.

Ask her what her husband is wearing, and say "Damn. DH is wearing that. Can your DH wear something else?"

Alpacajigsaw · 23/12/2025 18:05

i wouldn’t change, who cares. It’s Christmas Day in someone’s house, not a wedding.

CaptainMyCaptain · 23/12/2025 18:05

The whole idea of checking what a family nember is wearing on Christmas Day is so bizarre. Is it some Instagram thing for the photos? Wear what you like @Xmasdresscode

Pick your battles is very much a mantra that’s worth listening to

CarefullyCuratedFurniture · 23/12/2025 18:07

Are you Kate Middleton, and this is going to end up all over the Daily Mail?

Are you referring to the OP or the SiL? The whole idea is bonkers.

PInkyStarfish · 23/12/2025 18:09

My sister and I often dress alike, not on purpose, we have the same tastes.

It’s ridiculous to dictate to you that you can’t wear a similar outfit!

SillyNavyTiger · 23/12/2025 18:10

one of you will look a lot better than the other, and will make the other one look terrible in comparison let's be honest. I am guessing you look a lot better than her?

I purchased the outfit specifically for the day
sorry but that's very weird if it's just a day at you MIL 😂

MO0N · 23/12/2025 17:52

I'd say yeah sure, etc, then pretend I forgot

Wouldn't that worry your family that you had early dementia, how could you forget such a conversation?

Without knowing more details of the outfit its hard to say, do adults usually do outfit checks in advance?

I am not sure why insta would be an issue, she can just delete the OP from all the photos she's posting, so that can't be that.

Is she worried about how it will look on her Insta?

Probably, yep!

Just message her back a face palm emoji and "Sorry! Too late, I've not got anything else. Good job we won't be out together in public"

Paperwhite209 · 23/12/2025 18:15

Make sure you get up and dressed before her on Christmas Day 😂
