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.

Yanbu but let her know so she has the option to wear something different if she prefers.

YANBU- I’d still wear it. I also wouldn’t tell someone else they should change their planned outfit- I’d just laugh it off on the day about you ‘twinning’, keep it light hearted. It’s no biggie!

You can change your decision. She can’t.

She text me earlier to ask what outfit I’ve planned for Christmas Day (as we are all at MIL’s house this year).

That is so weird of her to ask and then to try to control what you do. Not impressed.

Barrenfieldoffucks · 23/12/2025 17:46

Depends...how close is close? You have options, she doesn't I guess.

CutePixieGirl · 23/12/2025 17:46

No one else dictates what I wear.

PennyLaneisinmyheartandmysoul · 23/12/2025 17:47

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

You can change your decision. She can’t.

Why does it matter though. DSIL sounds ridiculous trying to dictate what other people should wear.lon Christmas day.

BettysRoasties · 23/12/2025 17:47

I mean you shouldn’t have answered and said I don’t know yet.

Now if you do you can bet she will of told everyone that she told you she was wearing that already.

MumChp · 23/12/2025 17:48

Who cares. Sorry. Wear what you like.

ConnieHeart · 23/12/2025 17:48

How ridiculous. Who cares what anyone wears on Christmas Day?

UxmalFan · 23/12/2025 17:48

If wearing something similar matters to you, don't.
If wearing something similar would cause significant distress to SIL and you want to avoid that, don't.
Otherwise, wear what you like. I find it very strange that anyone would bother about this at a family lunch. If you were red-carpet celebs at a televised event, maybe.

hyggetyggedotorg · 23/12/2025 17:49

I’m assuming you didn’t reply “pyjamas”, which for me is slightly odd for Christmas Day in the first place 😂.

If it were me I would probably wear something else just to keep the peace but, honestly, things like this are batshit. It’s not like wearing the same as the bride at a wedding.

TheTowerAtMidnight · 23/12/2025 17:49

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

Flowerslamp · 23/12/2025 17:49

If you were going "out" I'd probably be glad we'd realised in advance and change, but I can't imagine caring that much for a day with ILs.

I'd probably call to actually talk about why it's bothering her, rather than try and deal with it by text.

JudgeBread · 23/12/2025 17:49

Pfff, my little brother and I managed to show up in the same outfit one year, he lost a bet with my other brother and had to wear a dress, which just so happened to be the same gorgeous sparkly green number I'd bought. Top that.

No but seriously wear what you want, maybe just use accessories to differentiate (so if she's wearing silver go with gold) or something. No one's going to give a shit.

Theunamedcat · 23/12/2025 17:51

I mean....do you dress up for Christmas day? Im mostly in comfy trousers and a tshirt unless im going out

FourCatMama · 23/12/2025 17:52

Wear your planned outfit and tell her "Great minds think alike"!!!

FourCatMama · 23/12/2025 17:52

Or :you got the memo!!!!!

Mistletoeiggi · 23/12/2025 17:52

Are you likely to look significantly "better" than her?

MO0N · 23/12/2025 17:52

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

TomatoSandwiches · 23/12/2025 17:54

I would juat wear what I wanted to... it is a bit odd she asked, does she normally do that for family get togethers?

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.

cantbearsed247 · 23/12/2025 17:55

I can't imagine getting a special outfit for Christmas day with my MIL or, like SIL, feeling the need to check that other people aren't wearing the same outfit as me. It's all too bizarre.

Tell her you bought the outfit specially so do want to wear it and don't mind at all that she is wearing the same thing.

FieryA · 23/12/2025 17:56

Its really rude of her to ask you to change your choice. So what if you are in similar clothes? I wouldn't change what I had planned, especially if I had bought accessories etc. to go along with it.
