The best women's fancy dress costumes are flattering, comfortable, and recognisable the moment you walk in. These are our favourite ready-to-wear options for 2026, from glamorous icons to funny one-and-dones.
How we chose: we favour complete outfits, recognisable looks, and costumes you can move and dance in. Every pick links to its product page, where you can check the current price. We also tag each pick with what it is best for and a rough price band (Budget, Mid-range or Premium) so you can choose fast.
Iconic and glamorous
1920s flapper
A 1920s Gatsby flapper dress is one of the most flattering looks going and it suits every shape. Add a feather headband and pearls and you are done. Ideal for a hen do or a Peaky night, and it moves well on the dance floor.
Pink Ladies (Grease)
The officially licensed Grease jacket is a hen-party and group favourite. Wear it over black jeans and a white tee, on its own or matched with a Sandy. The satin finish photographs brilliantly.
Cruella
A full Cruella kit with the cape, gloves and two-tone wig, so there is nothing else to buy. Strong on its own for a party and a reliable World Book Day choice. Add red lipstick to finish.
Mermaid
A sequin fishtail dress that turns heads and still lets you sit and dance, unlike stiffer mermaid tails. Comfortable enough for a full night despite the drama. Pair with shell hair clips for extra effect.
Eras and themed
ABBA disco poncho
Instant 70s disco: the sequin poncho reads as ABBA the moment you walk in. Great for a group where everyone picks a colour, or a Mamma Mia singalong. Slips straight over your own outfit.
60s go-go girl
A bright 60s mini-dress for a retro, Austin Powers-style look that is fun and easy to move in. Add white boots and bold lashes to lean into the era. Light and comfortable for dancing.
80s neon set
Tutu, leg warmers, fishnet gloves and jewellery in one affordable box. Layer it over a bright top or leotard for a full 80s Madonna look. The easiest way to nail the decade without piecing it together.
70s flower-power hippie
A flared 70s hippie dress that comes ready to wear, so there is nothing to assemble. Comfortable, colourful and quick to put on. Add a headband and round sunglasses for the full flower-power feel.
Funny and quick wins
Nun
A classic that always reads, and one of the warmest options here for a chilly October night. Full-length with a headdress included, so it is genuinely last-minute. Works for a saints-and-sinners theme too.
Pirate
A swashbuckler outfit that suits almost any party or theme. Add a sword and hat for a recognisable look in minutes. A safe choice when the theme is broad or undecided.
Roman toga lady
A floor-length toga with shawl and headpiece for an elegant, ancient-history look with full coverage and warmth. Comfortable to wear all evening. Gold sandals and a laurel finish it off.
Snow princess
A fairytale princess dress with a red hairband included, easy to wear and instantly recognisable. A reliable choice for World Book Day as well as a Halloween or winter party. Add a cape or fur trim for extra warmth.
