Masquerade Party Ideas: Masks, Food, Music and a Game for the Night

Masquerade party ideas for adults: Venetian masks and what they mean, dress code, candlelit decor, Carnival food, music and a game that ends in the unmasking.

A good masquerade party needs four things: a dress code everyone can meet (evening wear and a mask), candlelight, small food you can eat with a mask on, and one planned moment when everybody unmasks together. Give the night a game that builds to that unmasking and the rest takes care of itself. Here is each part, with the Venetian traditions behind it.

Start with the dress code

Put it on the invitation in one line: "Evening wear and a mask. Gloves if you have them. Masks stay on until midnight." That last sentence is the important one. If people take their masks off as soon as they get hot, the party becomes an ordinary party with props.

Make it easy to comply. A basket of plain masks by the door costs little and saves the guest who forgot. A mirror near the door helps people tie ribbons.

Masks, and what they meant in Venice

Masked balls come from the Carnival of Venice, which ends on Shrove Tuesday, the night before Lent. Guests like knowing what their mask is, so put a card by the spare basket:

MaskWhat it looks likeThe story
BautaFull face, a square jaw that juts outLets the wearer eat and drink without lifting it. Worn with a black cloak and tricorn hat.
ColombinaHalf mask over the eyes, gold, silver or featheredNamed after a maid in Italian comedy. The easiest one to wear all night.
Medico della pesteWhite, with a long curved beakThe plague doctor. Now one of the best-known Carnival masks.
MorettaSmall black velvet ovalHeld on by biting a button inside, so the wearer could not speak.
VoltoPlain white full faceThe everyday citizen's mask. Anonymous on purpose.
ArlecchinoBlack half mask, often with a red and black diamond costumeHarlequin, the trickster of Italian comedy.

Tell guests any mask is fine. The table is for conversation, not a rule.

Decorations: candles and very little else

A masquerade looks right in low light. You need less than you think:

  • Candles, as many as you dare. LED ones on the floor and near curtains.
  • Gold, black and deep red. A gold runner and a few black feathers in a vase do most of the work.
  • Mirrors. Lean one against a wall. Masked guests check themselves all night.
  • Signs on two doors, such as "CLOAKROOM" and "SERVANTS' STAIR". Small touches like these make the room feel like a palazzo.
  • Somewhere for photos: a plain dark wall, a candelabra and a chair.

Food and drink you can manage in a mask

Choose food that goes in one bite. Nobody wants to lift a mask to tackle a plate of pasta.

  • Cicchetti, the bar snacks of Venice: crostini with whipped salt cod (baccalà mantecato), sweet-and-sour sardines (sarde in saor), or simple ricotta and honey.
  • A board of cheese, cured meat, olives and breadsticks.
  • Carnival sweets: frittelle, small fried dough balls with raisins or cream, and galani, thin fried pastry ribbons dusted with sugar. Both are eaten in Venice during Carnival.
  • Drinks: prosecco, a spritz, or Bellinis (peach purée and prosecco), which were first poured at Harry's Bar in Venice. Make one big batch so you are not mixing drinks all night.

Music

Start with Venetian and Italian classical music, then move to waltzes. A starting list: Vivaldi's "Winter" from The Four Seasons, Offenbach's Barcarolle, Verdi's "Libiamo" from La traviata, the prelude to Verdi's Un ballo in maschera (a masked ball opera), Strauss's Blue Danube and Tchaikovsky's Waltz of the Flowers. Switch to whatever your guests dance to after the unmasking.

Give the night a game

Masks make people bolder. A game uses that. Ideas that suit a masquerade:

  1. Who is behind the mask? Everyone writes guesses on a card as they arrive. Score them at the unmasking.
  2. Best mask award. Vote on phones or with paper slips. Add "Best Waltz" and "Most Mysterious".
  3. A mask-making table for the first half hour, with plain masks, glue, sequins and feathers.
  4. A murder mystery that ends in the unmasking. Everyone plays a masked suspect at a Carnival ball. Nobody unmasks until the killer is named, then the room takes off its masks together before the reveal.

The last one gives the night a beginning, a middle and an end. Here is how a three-hour evening runs with it:

TimeWhat happens
7:30Guests arrive masked. Drinks, cicchetti, photos.
8:00Round 1. Everyone introduces their character, still masked. Two clues.
8:30Round 2. Secrets start to come out. Two more clues.
9:05Round 3. The last two clues. Accusations.
9:35The vote.
9:40Everyone unmasks together. Then the reveal.
9:50Dancing, dessert, awards.

On New Year's Eve, shift it so the vote opens at 11:45 and the room unmasks at midnight. Our New Year's Eve party games guide has the full night.

With Sleuth Night

We wrote Murder at the Masquerade for exactly this party. It is the last night of Carnival in Venice, 1888. Count Alvise Corvino is found stabbed with a glass dagger two minutes before he was to announce his daughter's engagement, and nobody may leave or unmask until the killer is named. It plays 6 to 14 guests, about two hours: three rounds of 20 to 30 minutes, then the vote and the reveal. Each guest gets a private link with their character, their secrets and a costume suggestion for their mask, and the clues show on your TV. The host plays too. Setting up is free and you pay $29 when you press Start Round 1. See the masquerade murder mystery party page for how the masks work in the plot, or the hosting guide if this is your first.

Questions hosts ask

What do you wear to a masquerade party?

Evening wear and a mask. Put it on the invitation as "Black tie optional, masks required". Gloves are a good extra. Keep a basket of spare masks by the door for guests who forget.

What do you do at a masquerade party?

Dance, drink and guess who is behind each mask, then unmask together at a set time. A game gives the night a shape: a murder mystery where nobody unmasks until the killer is named works well, because the unmasking becomes the finale.

What food do you serve at a masquerade party?

Small food you can eat with a mask on: Venetian cicchetti on crostini, cheese and cured meat on a board, and Carnival fritters (frittelle) or fried pastry ribbons (galani) for dessert. Prosecco, spritz or Bellinis to drink.

When should everyone unmask?

At a planned moment everyone can watch: midnight on New Year's Eve, or the end of a game. If it happens one by one through the night, the masks stop mattering by ten o'clock.

How many people do you need for a masquerade party?

Eight or more makes the masks fun, because guests really cannot tell who is who. For a murder mystery at a masquerade, ours plays 6 to 14.
