Costumes for every kind of event

Got a stag or hen party coming up? Heading to Pride? Invited to a summer carnival or fancy dress event? Whatever the occasion, Costumalia will help you find the perfect look.

Costumes as gifts

More and more children are asking for costumes of their favourite characters as birthday or Christmas presents. The most popular choices are superhero costumes and characters from fairy tales or films.

Accessories to complete your character

No costume is complete without the right accessories, which is why at Costumalia we’ve put together a huge range of extras to turn any outfit into a full character look:

Hats: cowboy hats, Mexican hats, sailor hats, top hats, firefighter helmets and much more.

Wigs: we have all kinds of wigs: short, long, colourful, curly and straight, so you can choose the one that suits your character best.

Swords, axes and weapons: essential for certain costumes, especially if you’re dressing up as a pirate, Viking, police officer, devil and more.

Masks and eye masks: from horror masks to Venetian styles, ideal for Halloween or Carnival.

Make-up: fake blood, latex, face paint, glitter... everything you need for the perfect finishing touch.

Tutus: what little girl wouldn’t want to include a tutu in her costume? Perfect for dressing up and playtime.

Decorations for celebrations all year round

As well as costumes and accessories, we also offer a complete selection of party decorations:

Halloween decorations: cobwebs, pumpkins, animated props, eerie lights and much more to turn your home into a haunted house.

Birthday decorations: balloons, bunting, photo booth props, themed disposable tableware and centrepieces.

Flamenco party decorations: flamenco-themed celebrations are popular year after year, and decorations make all the difference. Lanterns and plenty of colour are all you need.

Decorations for themed parties: Hawaiian parties, pirate parties, 80s parties, medieval celebrations and much more.

Gender reveal decorations: if you want to celebrate your baby’s gender reveal, decorations become especially important. Choose pink and blue details, and don’t forget confetti cannons or coloured powder to make the big announcement.

For the party hour: although accessories usually take centre stage during this part of the celebration, decorations also play a key role.

At Costumalia, we have everything you need to set the scene in any space and impress your guests.
