The most popular fancy dress themes for 2025

The fancy dress landscape is constantly evolving, but some themes remain favourites while new trends emerge. For 2025, we see an exciting mix of classics and innovative concepts in the world of carnival clothing and costumes. Traditional themes such as pirates, police officers and medieval figures remain popular due to their recognisable and timeless nature. These costumes are often available for all ages, making them perfect for family gatherings or group outings. Animal costumes also remain a popular option, with creations ranging from giraffes and pigs to peacock costumes, loved for their playful and accessible appeal.

For pop culture fans, there are costumes based on well-known characters such as Monopoly Man, Mario & Luigi, and various clown costumes that are always a hit at parties. Humor is at the heart of many 2025 fancy dress ideas, with costumes such as ‘man riding a chicken’ guaranteed to get a laugh. For kids, fairytale and fantasy costumes remain hugely popular, with a wide range of princesses, fairies and magical creatures to suit all genders.

Theme parties will also get a boost in 2025 with specific decade themes, with outfits inspired by the 80s being particularly popular. Halloween is gaining ground in the Netherlands, with more and more specialized costumes for the occasion. And of course, carnival remains a key player in the world of party clothing, with colorful, humorous and sometimes extravagant outfits that fit in perfectly with this Dutch and Belgian tradition.

The most popular costume themes for 2025 are:

Classic characters (pirates, medieval figures)
Occupations (police, doctors, firefighters)
Animals of all shapes and sizes
Pop culture figures from movies and games
Humorous and striking concepts

Group costumes and fancy dress for duos

A striking trend in the world of fancy dress is the increasing popularity of group costumes and duo outfits. Dressing up together creates a bond and increases the party atmosphere, whether it is with friends, family or colleagues. In 2025, retailers will offer extensive collections of themed clothing specially designed for groups of different sizes. Particularly popular are coordinated animal costumes, where a group of friends dress up as a herd of pigs or a flock of birds, for example, which always makes for hilarious photo moments at parties.

For couples, there are plenty of options for complementary costumes – think matching pirate couples, iconic duos from movies and series, or creative concepts like day and night. These costumes are carefully designed to tell a coherent story together, making them ideal for couples who want to shine together at a party. But there are also special combinations available for parents and children, which strengthen the family bond and create unforgettable memories.

The trend for group costume parties continues with themes such as disco, where a whole group of friends can transform into a dancing crew from the 70s or 80s. Professional themes are also popular, where teams can dress up as a group of doctors, chefs or superheroes. Retailers are capitalizing on this by creating special sections with group costume suggestions and even offering packages that include everything for a complete group experience.

The great thing about group costumes is that they are suitable for all occasions – from carnivals to Halloween parties, and from corporate outings to themed birthday parties. They not only provide a visually spectacular result, but also create a sense of togetherness among the participants, which takes the party experience to the next level.

Favorite Group Costume Ideas for 2025:

Animal groups (three pigs, safari animals)
Disco theme with glitter and platform soles
Film crews with different roles
Superhero families
Historical periods with different characters

Fancy dress for all ages and body types

The world of fancy dress is becoming increasingly inclusive, with options to suit all ages, sizes and preferences. Where costumes used to be limited in size, today’s partywear suppliers offer an impressive range of options. For adults, there is a huge variety of carnival costumes, from subtle themed outfits to lavish, eye-catching costumes. Teenagers can choose from trendy designs that suit their interests, while children can find safe, comfortable and imaginative options to spark their imagination.

Even the littlest ones aren’t forgotten, with adorable baby costumes that are as comfortable as they are Instagram-worthy. The growing focus on inclusivity has also led to a wider range of plus-size fancy dress, with adjustable costumes that flatter a variety of body shapes. Retailers like e-Carnavalskleding.nl offer special categories for different sizes, so everyone can enjoy the magic of dressing up without worrying about fit.

When it comes to gender specific costumes, there is a clear shift towards greater flexibility. While there are still traditional male and female options, there are increasingly unisex themes available, such as animal and fantasy costumes that can be worn by anyone. This reflects a wider societal trend towards gender neutral options in all aspects of clothing and accessories.

Accessories play a crucial role in personalizing fancy dress for different age groups. A wide range of hats, wigs, glasses, jewelry, capes, gloves and themed props allow everyone to customize their costume to their personal style or the specific needs of a themed party. These customization options make fancy dress accessible and enjoyable for people of all ages and backgrounds.

The main target groups for fancy dress:

Babies and Toddlers (Safe, Soft Costumes)
Children (imaginative and recognizable themes)
Teens (Trendy and Pop Culture Based Outfits)
Adults (wide choice for all tastes)
Plus size options (comfortable and flattering designs)

Practical tips for choosing the perfect fancy dress outfit

When selecting the ideal fancy dress costume, there are several practical considerations that can make or break your party experience. Comfort is at the top of the list, especially for costumes that will be worn for extended periods of time during carnival or Halloween parties. Look for materials that are breathable, allow for freedom of movement, and are appropriate for the season – a thick, plush animal costume might be perfect for an October Halloween party , but less so for carnival in the warmer spring.

Safety is another important factor, especially for children. Check that costumes do not contain any loose parts that could pose a choking hazard, and that visibility is not obstructed by masks or headgear . For nighttime events, such as Halloween, it is wise to choose costumes with reflective elements or brighter colors that improve visibility in the dark.

When it comes to group costumes, coordination is key. Plan in advance who will represent which character or element of the theme, and consider a “dress rehearsal” to see how all the costumes come together. Many retailers offer suggested group themes or even complete packages, which can simplify the planning process.

Budget considerations also play a role. Fancy dress can range from affordable basics to elaborate costumes with all the bells and whistles. Determine your budget in advance and consider whether you’re investing in a one-time costume or a versatile piece that can serve multiple occasions. DIY options, inspired by platforms like Pinterest, can provide a cost-effective alternative while also tapping into your creative side.

Finally, consider the practicalities of transportation and storage. Bulkier costumes such as animal costumes or costumes with large accessories can pose challenges when traveling to events. Some retailers offer compact packing options or costumes that fold easily for transportation.

Essential checklist for choosing fancy dress:

Comfort and freedom of movement
Seasonal suitability (temperature and weather)
Safety, especially for children
Budget and reusability
Transport and storage options
Completeness (are all necessary accessories included?)
