Stag do fancy dress ideas for the groom

The groom’s outfit sets the tone, so pick something that’s funny rather than cruel. He’ll be wearing it for hours, possibly on a plane or a train, so comfort matters more than you’d think.

  • The groom as the bride: a wedding dress and veil is the all-time classic. Grab a veil from our hen party accessories to finish it.
  • Fake naked suits: guaranteed laughs, and nobody actually has to strip off. They can be very warm though.
  • Retro fitness or 80s: shell suits and leotards are big crowd pleasers. Find more in our 80s fancy dress.
  • Superhero spin-offs: novelty superhero costumes work well for groups. See superhero costumes.

Stag party outfits for the whole group

Matching outfits look great and make it easy to spot your mates in a busy bar. Oktoberfest sets suit beer festivals and European city breaks, while inflatable costumes are brilliant for daytime chaos, though they’re not ideal for crowded pubs or long flights.

If not everyone wants a full costume, agree on one shared item instead. Matching hats from our fancy dress hats or silly specs from our party glasses do the job and fold into a bag.

One more thing: give the groom a costume that’s a step sillier than everyone else’s. It makes him the centre of attention, which is the whole point, and it means the photos tell the story without any captions.

Practical tips before you book

Check venue and airline rules if you’re travelling. Some bars turn away big groups in fancy dress, and fake weapons can cause trouble at airports, so leave any fancy dress props at home if you’re flying. Pack a change of clothes for the evening if the daytime outfit is very silly.

Novelty costumes often run small or come in one size, so check our costume size guide before ordering. If you’re still looking for inspiration, have a look at our men’s fancy dress or browse shop by theme.
