If you’ve ever been lucky enough to be invited to a Murder mystery dinner, you will know the party is HELLA FUN.
Picture this: an evening filled with suspense, clues in a dimly-lit dining room, not knowing what plot twist will you come across next.
But before you dive into the intrigue, let’s not forget the outfit is a huge part of the fun as well!

The right outfit can set the mood and make you feel like a character straight out of a whodunit novel.
Whether you’re channeling a glamorous detective or a sassy suspect, we’ve got the perfect style tips to help you shine at your next dinner party.
Ahead, I’ve gathered 20 cute outfits from real-life dinner detective looks to super fun costumes.
Let’s unlock the secrets to the ideal outfit for a night of mystery and fun – enjoy!
1. GO ALL GLAM
Most of the murder mystery dinner has a dark romance theme; think the speakeasy, mystic kind of vibes.
And if your dinner setting is dimly-lit, well, it’s the perfect timing to wear a bright color dress for a nice contrast!

A Barbie pink tube dress and statement gold clutch are serving looks in the most tasteful way.
A failproof way is wearing something with a gold accent and black so it’s as mysterious as it’s glamourous.

A split dress like this above can draw eyes upwards and can elongate your legs visually.
As a 5″3 girl, I am obsessed with all kinds of split dresses.
And guess what, looking sassy in a black dress together with some statement accessories works wonders.
Seriously I wanna join their parties – it seems wildly engaging and fun!
2. Suspender belt for a detective look
When it comes to the classic detective look, the suspender belt is THAT statement piece.
It’s one of a kind and gives a nice twist to an otherwise boring outfit.

By incorporate all kinds of stripes in this outfit, this all-black look is never a boring one.
And guess what, there’s nothing cooler than wearing black lipstick.
Not black red lipstick, not purple, not brown —just pure, inky BLACK MATTE lipstick.

For a sassy version, a black lace bralette and white shirt make the look.
This fit is just as smart as it’s alluring.
Be that irresistable girl in the mystery dinner party!
We decided to hand out 5 prizes at the end of the night.
I just got some nice amber apothecary jars from Target and filled them with Halloween candy. One prize was for who had the most fake money at the end. There was a suggestion in the party we bought, to hand out fake money at the beginning and people could buy secrets from other players.
Some people were really good at it! We also gave out a prize for the best actor and best actress. We gave out a prize for the person who guessed the murderer correctly (and first)! And the last prize was for best costume.
If you want to take this look to another level, add some blood stain and be the famous “Bonnie & Clyde”.

Partners in crime – till death did them apart.
I lovev the choice of shoes here – the T-bar heels just work wonders with this retro look.
Mob wife look anyone?

It’s as feminine as it’s fierce.
3. Be that mysterious maid
If you have already tried to cosplay the space smugglers, magical murders and Hollywood Hostages, well, what about a Hampton Maid who is as innocent as she’s mysterious?

The maid just calling to let you know we have a crime to solve! 🔎✨

This look is actually quite cute.
To match the mystery dinner theme, finish the look with fishnet tights and dark lipstick to give it an edge.
4. Couple look for mystery murder party
For a cute couple look, go old school.

For guys, think pinstripe suits, fedoras, and spectator shoes.
For ladies, flapper dresses and feather headbands always do the trick.
5. The 1920s Gangster and flapper mystery party
This look just never gets old.
Whether you are going for a speakeasy party or mystery murder night, these dresses are just so serving.
If you want to go all in, get a retro hairstyle and statement pearl necklace to complete the look.

Ladies, black or cream?

I literally want both.
6. The white braid in the scene
Whether it’s for Halloween or a Mystery dinner party, this bloody braid look is just one of a kind.

Commitment issue?
“I’ve been committed to myself since I was Born.”
7. THAT fake socialite look — so you can wear whatever you want.
When your role at a socialite murder mystery party is to dress as a light academic poet.

Already getting kind of suspicious….
Trust no one babe.
Trust no one.
8. Sherlock Holmes but sassier
The sassiest way to wear a cape?

Well, with the white corset, mini skirt, and a tie.
The sassiest Sherlock Holmes for real.

And this look is equally seductive.
I mean, that’s a good strategy to distract the other joiners with blank sheer tights, isn’t it?
9. Sherlock Holmes – schoolgirl version
Is that just me or this look is giving an edgy Korean style?!
I desperately want to try this look out.
10. Murder Mystery party funny costume
If you wanna go for another route for the murder mystery party, go as silly and fun as you want because, why not?!

I am definitely feeling this bloodied shower curtain is gonna turn heads in the crowd.
Get the party started!
11. Stay effortless with a murder theme tee
I like murder shows, comfy clothes, and maybe 3 people.

Can’t be more accurate…

I’m here to meet my partner in crime.
