The best 70s fancy dress ideas come down to a few loud signatures: flares, sequins, bold prints and big hair. Pick a disco look, a glam pop star or a flower-power hippie, then layer on the platform shoes, medallions and round shades that sell the decade. The pieces below cover men and women, so you can build a single costume or kit out a whole group.

How to get the look: start with one statement piece, a jumpsuit, a flared suit or a sequin dress, then finish with platforms, a wig and an accessory set.
70s looks for women
Flares and a wide collar do most of the work. A jumpsuit gives you the whole silhouette in one buy, while a flared-sleeve dress leans more hippie and boho.
70s disco jumpsuit
The full disco silhouette in one piece. A flared blue jumpsuit nails the look the moment you put it on, then you just add shoes and shades.
Flare sleeve disco dress
A softer, boho take on the 70s. The wide flared sleeves and retro print work for both a disco party and a hippie theme.
Finish with platform shoes or knee-high boots, hoop earrings and a centre-parted or feathered wig. Round sunglasses pull the whole thing together.
70s looks for men
Think bell bottoms, an open-chest shirt and a wide collar. A full set saves you hunting down each piece and gets the proportions right.
Men's disco set with bell bottoms
Flared trousers and a wide-collar shirt in one set, so the cut and proportions are sorted. Open the shirt at the chest and you are there.
Retro 70s outfit for men
A second bell-bottom option with a bolder retro print, handy if you want two men matching in a group. Add a medallion and an afro wig to finish.
Disco glam and ABBA
For an ABBA or pop star look, turn up the sequins and the colour. A multicoloured diva costume reads instantly as 70s disco on a dance floor.

Bright, multicoloured and made to stand out. This is the one for an ABBA tribute or a glam disco theme where you want to be seen.
Accessories that sell the decade
The small details finish a 70s costume. A ready-made accessory set saves you piecing it together one item at a time.

The finishing kit in one buy, so you are not chasing each piece. Drop it over any flared outfit to push it fully into disco territory.

Frequently asked questions
What should I wear for a 70s fancy dress party?
Start with one statement piece: a flared jumpsuit or a sequin dress for women, or bell-bottom trousers with a wide-collar shirt for men. Add platform shoes, a wig and round sunglasses, then layer on hoop earrings or a medallion to finish.
What is the difference between a disco and a hippie 70s look?
Disco leans glam: sequins, bright colours, platform shoes and shine. Hippie leans earthy: flared sleeves, floral prints, headbands and a boho feel. Both sit in the 70s, so pick the one that suits your party.
How do you do an ABBA costume?
Go bold and sparkly. A multicoloured or sequin disco outfit with flares reads as ABBA straight away, especially in a group of four. Add platform boots and feathered or centre-parted hair.
Can men and women do a matching 70s group costume?
Yes. Put the men in bell-bottom suits and the women in flared jumpsuits or sequin dresses, keep the colours in the same family, and add matching shades and medallions. A coordinated group reads stronger than a single costume.
What shoes go with a 70s outfit?
Platform shoes or platform boots are the giveaway. Go for a chunky heel and a thick sole in a bold colour, and keep them comfortable enough to dance in all night.
