If you’re searching for the perfect girl’s superhero costume, you might as well start with the iconic Wonder Woman. Flowing red cape? Check. Sparkly starred skirt? Check. Jewelled golden headband? Check. DC’s awesome Amazon princess has been fighting crime, battling oppression and smashing the patriarchy since 1941. That’s a pretty powerful superhero message to empower our young girls today.

She commands plenty of respect from the grown ups too. “My little wonder niece loves this,” said one proud auntie on the John Lewis site. “Great quality/value for money and shows everyone just what a sassy little girl she is.”

Your little one will enjoy fighting crime and righting injustice, or perhaps more likely tearing around the garden burning off energy.

Black Panther’s cat-like reflexes and agility are a perfect match for an energy-filled pre-schooler.

The bright red pants are over the legs, with a sweet little abs pattern on the chest, and of course the instantly recognisable S logo.

Gold details on the belt and embellishments on the cuffs add to the appeal, as well as the detachable cape, essential for any crusader. When Gotham City needs protecting – or maybe just the living room – your child will be able to spring into action. Batman is a playground favourite, as this Argos reviewer confirms. “What more can you ask for than a very happy little grandson,” she said. “ He loves playing his superhero.”

This fab superhero has been looking after the city since the early sixties, most often as the alter-ego of super librarian Dr Barbara Gordon. Superhero skills AND super-smart too…she’s a fantastic role model.

This costume comes with that all-essential swirling black cape, and a mask to provide the required superhero disguise. It’s got a full tulle skirt too, as well as the gold bat emblem on the chest.

10. Classic Child Kids Warner Bros Robin, £15.79

Size: 3 to 4 years | Material: polyester

Every superhero needs a sidekick, and if you’ve got two little ones then it’s the perfect chance to have your very own Robin at home alongside Batman or Batgirl. The Boy Wonder is a best friend for Batman, helping him fight crime and always managing to save the day. His tales of daring were inspired by that other Robin, memorably stealing from the rich and giving to the poor in Sherwood Forest all those years ago.

This Robin costume will bring your miniature superhero up-to-date with his bright yellow cape and cheerful red and green costume. The stretchy jumpsuit has a muscly padded chest and of course an eye mask to keep your toddler incognito.
