To dress as Wonder Woman you need three things: a red and gold bustier with a blue star-spangled skirt or shorts, a gold tiara, and gold cuffs. Add long dark waves and a bold red lip and you read as Diana straight away. The pieces below cover the full look for women and kids, from a ready-made costume to a tiara-and-cuffs version over your own clothes.
How to get the look: start with the main costume, which does most of the work, then add the tiara and cuffs, sort the kids in the group, and finish with the hair and makeup.
The main costume
The fastest route is an official ready-made costume. It gives you the bustier, skirt and emblem in one buy, so you are not piecing it together. The classic comic look stays the most recognisable, with the battle-armour film version a close second.
Wonder Woman adult costume
The official Justice League dress with the red bustier, blue skirt and gold emblem in one buy. Sizes run from UK 8 upward, so the whole group can match.
Tiara, cuffs and accessories
The accessories are what tie the costume to the character. A gold tiara with the red star and a pair of gold cuffs will turn a plain red top and blue skirt into Wonder Woman, so they are worth getting right even on a budget build.
Wonder Woman tiara
The gold headband tiara with the red star is the single piece people recognise first. It works over your own hair and finishes any version of the look.
Wonder Woman cuffs
The official gold gauntlets give you the matching pair of cuffs that complete the accessories. Pair them with the tiara for a tiara-and-cuffs look over plain clothes.
Wonder Woman for kids
The same look scales down for children for a family group or a school superhero day. An official kids costume keeps the colours and emblem right without any DIY.
Kids Wonder Woman costume
The official Warner Bros classic costume for children, sized for ages 6 to 8. It matches the adult colours so a parent and child can go as a pair.
Quick kit and group looks
For a fast costume over your own clothes, an accessory kit bundles the key pieces in one go. Wonder Woman also works as part of a Justice League group with a Superman, a Batman or a Flash, or as a couple with a Steve Trevor.
Wonder Woman accessory kit
An official kit that gathers the key accessories in one buy, so you can build the look over a red top and blue skirt. The quickest way to kit out a group.
For the hair, go for long dark waves, loose rather than styled, and finish with a bold red lip. That pairing does as much as the costume to sell the character.

Frequently asked questions
What do you need for a Wonder Woman costume?
Three core pieces: a red and gold bustier, a blue star-spangled skirt or shorts, and the gold accessories, which are the tiara and cuffs. A ready-made costume covers all three, or you can build it from a red top and blue skirt with the tiara and cuffs added on top.
How do you make a Wonder Woman tiara?
The easiest route is a ready-made gold headband tiara with the red star, which sits over your own hair. For a budget DIY version, cut the shape from gold craft foam and add a red star, then attach it to a headband.
Can children dress as Wonder Woman?
Yes. Official kids costumes come in age ranges from around 3 to 10 and keep the same colours and emblem as the adult look, so a parent and child can match. Add a child-sized tiara to finish it.
Can you do Wonder Woman as a couple or group?
Yes. Pair the look with a Superman or a Steve Trevor for a couple, or join a Justice League group with a Batman, a Flash and an Aquaman. Matching official costumes keep the colours consistent across the group.
How do you style your hair and makeup for Wonder Woman?
Go for long dark waves worn loose, with a bold red lip and defined eyes. If your own hair is short or fair, a long dark wig gives you the same effect under the tiara.
