Every birthday party needs this

A few things belong at every party, from a child’s birthday party to a themed celebration for adults. Treat your guests to a birthday cake, snacks, and drinks. For enjoying the food together, you’ll need:

  • Paper cups
  • Paper plates
  • Paper bowls
  • Napkins

Finger food is naturally the best choice, as it can easily be transferred to the plate and then into your mouth. Your guests can also sample all the delicious treats.

The decorations adorn not only the birthday table but the entire room. Common choices include:

  • Garlands
  • Bunting
  • Streamers
  • Balloons
  • Photo wall backdrops
  • Theme decoration sets

Kostümpalast tip: Use the theme for the decorations as well as the food and drinks. Cake and lemonade do more than satisfy hunger and thirst—they also have a decorative effect. So showcase your theme on the buffet: A Hawaiian party delights guests with pineapple pieces and coconut treats, while a barbecue is perfect for a pirate party. Unleash your creativity and delight your loved ones!

Birthday decorations for children


Children love parties. A brightly decorated room or garden, cake and other treats, games with friends—what could be better? Keep their age in mind, because what is a hit this year may already be a thing of the past next year. Everyone also enjoys variety, and there is plenty of it when it comes to decorating themes. Whether it’s detectives, monsters, princesses, mermaids, or the latest favorite movie, a theme makes the party unforgettable. The games can be adapted to match it too, creating fun and lasting memories.

Decorate the adults-only party beautifully


Wildly colorful, elegant, or spooky: As an adult, you’re allowed to have fun on your birthday and forget about everyday life for a few hours. Choose a theme or opt for elegant decorations that are a little more subtle but still make the day special.

Decorations for all ages

Birthday decorations such as garlands, honeycomb balls, and paper fans are suitable
for any celebration. In summer, palm tree balloons and other themed decorations are a hit.

With a theme, you have another way to make your party unique. Wear costumes that match the theme! Dressing up is great fun. We have everything you need ready for you. Depending on the design, you can take the costume out of the closet again for another occasion.
