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.

I've never heard of a special outfit for Christmas Day in my whole life. Do you mean you dress up as a particular thing or do you just wear matching colours in normal clothes? I've always thought that even Christmas pyjamas or sweaters look awful and are a total waste of money. Maybe I'm just a miserable old woman...

How similar?

Are you in matching Pierrot outfits?

If not, she's insane. No-one cares. It's family, not a competition.

(If yes, you're both insane obvs)

Sunshineo · 23/12/2025 19:16

What are the outfits? How similar? Can you tell us if we promise not to copy?

Just wear it, make a joke about good taste and have a lovely day.

Adorable

If she was concerned she should have asked while home to have other options

cooldarkroom · 23/12/2025 19:19

If she is stick thin & you are not, You will be scrutinised anyway. So as much as this whole scenario is batshit. (Who checks who is wearing what to a family meal? ) I would just wear something else & when you see her, tell not to ask another time, because you wont be telling

How arrogant is sil @Xmasdresscode ! Thinking she gets to dictate your clothes?! Total arse! You wear your outfit you planned!

Exactly this, who tells someone what to wear?
If she's that bothered she should go to the shops tomorrow and pick out something else.

Threeboystwocatsandadog · 23/12/2025 19:24

YANBU to wear whatever you want but you know that if you wear your planned outfit SIL is not going to be happy. I suppose it depends how much that matters to you. I can tell you, as a mother of three, stepmother of three and grandmother of many, comprise is my middle name. Thirty four years of family harmony hasn’t been achieved without a lot of it.

SaltyCara · 23/12/2025 18:52

Ah, OP, if your SIL is generally a nice person and you have a friendly relationship with her and you feel she will appreciate it then just wear something else and feel good about yourself.

What if OP feels good about herself in her outfit, and doesn't want to change just to fit an absurd shibboleth?

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

Surely you don’t look silly wearing similar to someone in someone’s home when you’re with family. Who will care?

Butchyrestingface · 23/12/2025 18:43

Well, you know what the Queen said to Thatcher when she tried that line, don't you?

No. What was it?

Eggcheese · 23/12/2025 19:28

I met up with friends last night and I genuinely couldn’t tell you what they were wearing…so bizarre.

Beachtastic · 23/12/2025 19:29

I can never understand the tizz about this sort of thing. If someone was wearing identical clothes to me, I'd think it was brilliant!

usedtobeaylis · 23/12/2025 19:31

I'm amazed that anyone cares about this. Who gives a fuck if they're wearing the same thing?

Coconutter24 · 23/12/2025 19:34

Sparkletastic · 23/12/2025 17:46

You can change your decision. She can’t.

If it bothers DSIL that much she can go buy an alternative.

SurferRona · 23/12/2025 19:35

Why am i immediately thinking that your view is that you’ll look better than her in your similar outfits? I’d swap it up, it is Christmas! Tell her it’s an extra gift 😁 Did she perhaps feel so inspired by your plan (who plans Xmas day outfit so early in the year?!!!) she kinda accidentally stole it?

in case we’re sharing (haven’t RTFT) I’m in navy cashmere lounge set in the morning for gifts n scrambled eggs etc then a brushed cashmere jumper with dull gold/platinum lambskin leggings. So I can walk the dogs too 🥰

CaptainMyCaptain · 23/12/2025 19:37

I don't know what I'll be wearing on Christmas day yet. I certainly haven't bought anything new specially.

chickenfucker · 23/12/2025 19:39

If you don't care about matching and pissing her off wear what you've planned, if you care about either of those things wear something else.

CaptainMyCaptain · 23/12/2025 19:27

No. What was it?

Thatcher was told by Buck Palace that the Queen never notices what other women are wearing. In other words....Get back in your lane Margaret!

She wanted to know what the Queen was wearing to an event, so they didnt clash. The arrogance of the woman, assuming that she was so important that people would care!

AngryLikeHades · 23/12/2025 19:58

Moretwirlsandswirls · 23/12/2025 17:54

That’s ridiculous! I would laugh and say “we can be twins, so lovely we both have such fabulous taste”. I would think it was brilliant if my SIL turned up in the same outfit as me.

This.
I went to a girl's school and they cared about this back then as teenagers, but I don't think it matters in the least.
Wear the outfit.

Who cares. Sorry. Wear what you like.

Came on to post this! A right slap in the face to Peggy T....

Christmascherry · 23/12/2025 20:09

Ah I remember those days. When you still think people are there to give a shit about your outfit choices 😆. I’m assuming SIL is either still quite young, or doesn’t have much else to think about in her life. The reality is for a family Xmas event everyone is focused on the day or some other thing and no one cares about what you actually wear. I’d just wear whatever you want to wear OP.

Cherrysoup · 23/12/2025 20:10

I wouldn’t change. Are we talking absolutely identical?

My Dh finds it hilarious that my family has ‘Christmas clothes’, not necessarily new outfits, just something nice, mostly because we go to church in the morning then round to a family member’s house for the day.

Misanthropologie · 23/12/2025 20:12

What the hell does it matter? Is this Christmas gathering going to be in Hello Magazine?
