Retro Futurism: 70s Disco Meets Space-Age Fancy Dress for 2026

70s fancy dress is flared trousers, wide collars and disco colour, and in 2026 it has picked up a partner in space-age costume. Our own search data shows "70s fancy dress" pulls in roughly 1.5 times the combined search impressions of every other 70s term in our top search queries, from "disco fancy dress" to "1970s fancy dress", so we have built this round-up around both: one disco warm-up, then three space-age pieces.

What counts as 70s fancy dress

70s fancy dress usually means the disco look: flared trousers, a wide collar or shirt, and colour loud enough to read from across a dancefloor. Retailers and shoppers use "70s fancy dress", "disco costume" and "1970s costumes" more or less interchangeably, and on our own site the men's version of the search runs well ahead of the women's: "70s fancy dress mens" carries roughly 1,841 impressions over the last 90 days against 665 for the women's phrasing, and the men's version also ranks better on average (position 11.3 against 21.3).

The look itself is simple to build correctly. A flared trouser leg, a shirt or jacket with a properly wide collar (not a modern notch lapel), and one loud print or metallic finish get you most of the way there. Our full range sits on the 1970s costumes hub, and if another decade fits the brief better, our aviator and pilot fancy dress and rock and pop star fancy dress guides cover two more eras worth raiding.

Why space-age is 2026's fancy dress pairing

Space-age costume earned its place next to 70s fancy dress this year because 2026 delivered three space and sci-fi moments in the same year. NASA's Artemis II mission launched on 1 April 2026, carrying astronauts Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen on a roughly ten-day lunar flyby before splashdown on 10 April, the first crewed mission to leave low Earth orbit in over fifty years. Cinemas followed with Project Hail Mary, the Andy Weir adaptation starring Ryan Gosling, which opened in March 2026 and has since moved to streaming. Toy Story 5 landed on screens over the summer and brought Buzz Lightyear's space-ranger look back into the cultural conversation right as autumn party season starts.

In a 2026 Butlin's-commissioned survey of 2,000 people, 33% said fancy dress creates "a more relaxed, playful atmosphere" and 32% said it makes them feel more confident. Pairing a decade everyone recognises with a sci-fi trend everyone has just watched gives a group two conversation-starters in one theme, and nobody has to explain a niche reference at the door.

Four looks for 2026, from disco warm-up to space-age spectacle

The order matters here: one disco costume to open the night, then three space-age pieces that get louder as you go. Every product below is a real MorphCostumes design from our own catalogue, not a mockup.

4. Mens Disco Dude 70s Costume Shirt

The MorphCostumes Mens Disco Dude 70s Costume Shirt opens the night: a shimmering iridescent-spotted shirt with functional front buttons, made from 100% polyester. It is shirt only, so pair it with your own trousers or a pair of flares, and it runs six adult sizes, S to 3XL, sized the way you already buy shirts rather than off a costume-specific chart.

3. Men's Silver Astronaut Suit Costume

The MorphCostumes Men's Silver Astronaut Suit Costume is a metallic silver all-in-one with a front zip, padded collar, chest and sleeve badges, and an attached belt. It comes in three adult sizes, Medium to X-Large, sized by chest measurement, and it is the pick that reads as classic space-programme silver rather than a film costume.

2. Alien Morphsuit

The Alien Morphsuit is where disco hands off to space-age: a solid green, head-to-toe second skin in 91% polyester and 9% elastane, with a 4-way stretch that moves with you all night. Like every MorphCostumes design, it starts from a 125GSM+ breathable fabric baseline. Sizing is by height band, Medium (5'5"-5'10") to XXL (5'10"-6'5"), not by chest.

1. Mens Jet Pack Inflatable Costume

Our top pick, and the least subtle thing on the list: the MorphCostumes Mens Jet Pack Inflatable Costume straps on as a giant inflatable rocket, with a built-in fan that holds its shape for over four hours on four AA batteries. The batteries are not included, so buy them when you buy the costume rather than hunting for them on the night. It is one size fits most adults, and there is a built-in pocket so you can still reach your phone.

Make it a duo: pairing disco with space-age

Pairing works best as one disco piece and one space-age piece worn side by side, so the "meets" in the title actually shows up in the room. A Mens Disco Dude 70s Costume Shirt next to a Men's Silver Astronaut Suit Costume reads as a deliberate theme rather than two unrelated outfits: one of you is dressed for 1976, the other for 2026. Swap the astronaut for the Alien Morphsuit and you get the same contrast with a quieter, one-piece second costume, and the Morphsuit's 4-way stretch means whoever wears it can dance in it rather than stand at the edge of the floor.

Group organisers get an easy split too: put half the group in 70s disco pieces and half in space-age pieces, and the two sides photograph as one coherent theme without anyone needing to match exactly. The only piece worth planning around is the Jet Pack Inflatable Costume: one per group is plenty, and whoever wears it needs a clear route to the dancefloor.

Sizing and fit across the range

The sizing basis is not the same on all four, and that is the part that trips people up. The disco shirt goes by standard adult clothing size; the astronaut suit goes by chest measurement; the Alien Morphsuit goes by height band, since a Morphsuit's 4-way stretch fabric has to reach top to toe rather than fit a chest measurement; and the Jet Pack Inflatable Costume is one size fits most, held in shape by its own fan rather than a fitted cut. Two separate checks sit behind every MorphCostumes design regardless of that basis: garment techs measure every prototype across 30+ points at the design stage, and our QC team runs 500,000+ individual checks a year on top of that. If you are between two sizes on any of these four, size up rather than down.
