My surprise 40th birthday party (that I dont know about)

71 replies

Oldgalgames · 21/07/2026 06:38

My husband slipped up and has planned a surprise 40th for me in a couple of weeks. He has asked me to 'pretend' I dont know about it on the date and act surprised, no idea how its going to go, as a side note I did not want a party at all and I certainly wish I didnt know about it now. Anyway I am now at a loss on what to wear, i spend most of my time in gym clothes and i am not someone who is dressy or glam. I do have a lovely top from M&S https://www.marksandspencer.com/slash-neck-sleeveless-peplum-top/p/clp60778050?color=BLACK&extid=ps_ps-pla-pmax_ggl_ww_ch__-UK-_-_bau_tier1&cq_src=google_ads&cq_cmp=23464567334&cq_con=&cq_term=&cq_med=pla&cq_plac=&cq_net=x&cq_plt=gp&gclsrc=aw.ds&gad_source=1&gad_campaignid=23459513439&gclid=Cj0KCQjwjvfSBhDpARIsAEiOpSudUTnCWoQqAObIBFTqbay8SDMth7QDCawgRi631KQgrG-PebLy1tkaAssiEALw_wcB but what to wear on the bottom half? I am slim size 10 and 5f 7inches

So sorry your DH has done this, I would tell him once again I do not want a party. I would then go out by myself for the day so there’s non way I’m at the surprise party. You are allowed to not want a party.

just have your normal clothes on you are comfy in op it’s your special day no one else’s x

butnotlikethatanymore · 21/07/2026 11:08

And the person who suggested cycling shorts with that top? Seriously? Have a missed a fashion trend?

Erm … yeah … 😄

That’s a terrible suggestion! Good grief.

Some peeps are so funny. 😹

(For my own 40th party at The Ritz I wore a pinstriped Georges Rech suit - jacket and beautifully tailored shorts. But that was the middle of winter about a century ago. If I were 5’7 and size 10 the outfit I’ve suggested is exactly what I would choose for a ‘surprise’ party. Not actual padded cycling shorts, obvs. The kind I’m wearing to yoga right now. Plus whatever mildly celebratory footwear the OP just happens to have in her sports bag.)

Mosaic80 · 21/07/2026 11:15

The top is lovely! I'd just style it with cream jeans similar to how they have, I'd probably go for straight cut like this: https://www.uniqlo.com/uk/en/products/E482279-000/00?colorDisplayCode=01&sizeDisplayCode=027&pldDisplayCode=033

@Trainup @Megifer

I’d be cross at who organised it,
you wouldn’t?

your friend who is known for only wearing gym clothes has a surprise party arranged and then arrives all dressed up for a fancy do?

wouldn’t make you suspicious?

it seems the only ones who don’t know it’s a surprise are the guests.

damemaggiescurledupperlip · 21/07/2026 11:25

Get your hisband to send out a dress code memo, and make sure it is pitched right for you - jeans and a nice top , or whatever. Then you will all be on the same plane. If it’s at a restaurant, he will presumably have told you beforehand so you can dress appropriately - the surprise bit will be that you won’t know it’s more than the two of you - so no one will expect you to be in gym clothes

Minimeeny · 21/07/2026 11:28

Its a really weird situation.

If you dont want a party just dont have one.

But it feels so weird to think you are going to be faking surprise at a party you dont even want

Gonnagetgoingreturnsagain · 21/07/2026 11:35

The last 50th birthday party I went to the birthday girl had a gold sequinned top and plain trousers.

Would I be cross at the organiser if the birthday girl arrived looking like she'd been told she was being taken out for a meal?

No 😂

Oldgalgames · 21/07/2026 11:42

Thank you for all your feedback, i didnt expect so many comments.

I suspect DH intentially slipped up to be honest, i wasnt happy as I specifically said a party was not what I wanted. I had a party for my 30th and my circle of friends is much smaller now I am hitting 40. He did offer to cancel it but then I felt guilty and abit of a killjoy so here we are.

I dont know who I am pretending for, the guest I supose who all sound invested in it now. I really wish I didnt know about it.

I should clarify I wouldnt wear gym clothes for a meal out but I would be casual. This top still has its tags on and has been sat in wardrobe for about 6 weeks. I was wondering if wide legged jeans might be an option that could work?

OP posts:
BIossomtoes · 21/07/2026 11:44

Wide legged jeans would be perfect.

Unexpectedlysinglemum · 21/07/2026 11:46

I would wear that with a black satin midi skirt from Zara

seanconneryseyebrow · 21/07/2026 11:47

I got this recently for a casual wedding reception in a scruffy pub. I felt awesome in it and got heaps of compliments. Im 5'9" and got the tall version and it could have been longer tbh. Id still get the tall at 5'7'. It fit so well Im getting the black too. You might need to size down - Im a 10/12 and the 10 fit but I wish id got an 8 now.

Crafted from breathable linen, this wide-leg jumpsuit will see you through the months ahead across parties, weddings and dinners out on holiday. Shirring on the back and darts ensure a perfect fit on the top and the billowy sleeves add balance.

TheSunnySwan · 21/07/2026 12:24

Completely of topic if you don't like party's or want one why has your gone ahead and booked one . Just wear what you feel comfortable in

mrsscroodledoodle · 21/07/2026 14:32

Yes, wide legged jeans - lovely. Jobs a gooden.

Needmorelego · 21/07/2026 14:38

I'm sorry but if I didn't want a party I'd be really angry over this.
A party you don't want and having to worry about wearing the "correct" outfit.
Two things I personally despise.
Tell him to cancel and DON'T FEEL GUILTY.
It's your birthday. Not his and not whoever he has invited.

Trickedbyadoughnut · 21/07/2026 14:55

Yes, I think wide-leg jeans would be good with that top - something you're comfortable in would be top priority.

I do agree with others that you should just tell him to cancel if it's not what you want to do. You'd already been clear about that, it's not you who should feel guilty!

autumn1610 · 21/07/2026 15:11

I’d wear similar to the model. Nice jeans or a cigerette leg trouser

BreakingBroken · 21/07/2026 15:26

I like the top a lot, black trousers (any length or width) or jeans (any length or width).
Should you happen to spot a jumpsuit between now and then that’s not a bad call.

Oldgum · 21/07/2026 18:07

hang on. You explicitly said you didn’t want a party and he thought “screw that, I’m planning a party”?

Obimumkinobi · 21/07/2026 09:10

Surely the 'surprise' is the party but usually the birthday person knows their going out for a meal, so dressing up would be fine. Smart trousers of any colour would look good with your top.

Unless OP has crippling social anxiety (in which case, it is weird/cruel of him to arrange a surprise party for her) I'd try to take his gesture in the spirit in which it was presumably intended. At the very least, it will be nice to see loved ones.

This is a classic Mumsnet quandry - a DH does nothing and disappoints or does something and gets it wrong. Perhaps husband swapping is the answer? 😄

I’m up for it—can’t be any worse! Could I have a younger one though please 😊

gmgnts · 21/07/2026 22:41

When DH was approaching his 60th birthday, he announced that any surprise party would rapidly be followed by a surprise divorce! I didn't organise a thing and we were both much happier for it.

user1492757084 · 22/07/2026 01:05

Crisp, ironed with point wide legged white jeans and healed strappy shoes or sandals in neutral, black, metalic or bright colour. Sunglasses, hair and make up smart.

SaySomethingMan · 22/07/2026 05:49

Please ignore the advice to be angry about the party, again. You’ve already expressed your displeasure but have moved on.
He’s trying to do a nice thing. I get you’ll enjoy it on the day with your selection of friends and lives ones. Enjoy your day.

Thawtfulpanda · 22/07/2026 05:52

I would book a trip away with work.

Someone explicitly tell me that they really don’t want a party - I listen to them.
