Kids Lego Costumes
Our kids Lego costumes come from the LEGO Ninjago series: Kai in red and Lloyd in green, each as a foam minifigure tunic, a printed ninja jumpsuit or a full deluxe set, covering ages 4 to 12 between them. All of our kids' products are safety tested by accredited labs, and every costume goes through over 30 measurement checks.

Lego man or ninja: two looks for kids
A "Lego man costume" for a child comes in two shapes here. The minifigure look is a boxy foam tunic worn over your child's own clothes, with a moulded Lego head mask and a pair of Lego hands. The ninja look is a printed jumpsuit with shoulder pads, belt and vest detail built in, under a fabric hood that leaves the eyes open. Neither is a yellow brick-head suit: the head is Kai's or Lloyd's.

For the minifigure shape in red, the Kids Lego Ninjago Kai Legacy Basic Costume is a foam tunic, a moulded Kai head mask and a pair of Lego hands, one size up to 8 years old. The sword is sold separately. |
Lloyd fans get the same build in green: the Kids Lego Ninjago Lloyd Legacy Basic Costume packs a green foam tunic, a moulded Lloyd head mask and Lego hands, again one size up to 8 years. |

Older children after the show's outfit rather than the toy's shape have the Kids Kai Legacy Jumpsuit Classic Costume: a soft red jumpsuit with attached shoulder pads, belt and printed vest detail, plus a Kai hood mask. Sized Small (4 to 6 years), Medium (7 to 8) and Large (10 to 12), and its listing says to size up if your child sits between two. |
Green ninja, same cut: the Kids Lloyd Legacy Ninjago Costume pairs a one-piece Lloyd jumpsuit with a ninja mask. Its listing carries no age band, so measure your child against the size guide first. |

Where the whole outfit needs to come in one box, the Kids Lloyd Legacy Deluxe Costume brings the minifigure tunic, matching trousers, a moulded Lloyd head mask and a pair of hands together, Small (4 to 6 years) to Large (10 to 12 years) against the height and chest chart on its listing. |
Finish any of them with the Kids Lego Ninjago Throwing Stars Toy Set, a pair of gold toy throwing stars from the show, lightweight and with no sharp edges. |

Choosing a kids Lego costume by age
Up to 8 years, the Basic tunics fit in one size and go on over ordinary clothes, which suits a child who wants the costume off again ten minutes into the party. Across 4 to 12 years, the jumpsuit and deluxe styles run Small, Medium and Large, checked against height and chest measurements on the size guide rather than by clothing size; Medium ends at 8 and Large starts at 10, so a 9-year-old goes by the chart. The Basic and Deluxe masks are moulded heads that cover the whole face, while the jumpsuit hoods leave the eyes open, so try the head mask on at home before a long day in it and allow for softer vision on kerbs and steps. Beyond Ninjago, our kids ninja costumes cover black, red and dragon styles, and the rest of our kids costume themes sit one click away.
Frequently asked questions
What kids Lego costumes do you sell?
Five LEGO Ninjago fancy dress costumes across two characters, Kai and Lloyd: each as a Basic foam tunic set or a Jumpsuit Classic, with Lloyd also in a Deluxe tunic-and-trousers set, plus a matching throwing stars accessory.
What age does a kids Lego costume fit?
The Basic tunics fit up to 8 years in one size. Jumpsuit Classic and Deluxe come in Small (4 to 6 years), Medium (7 to 8 years) and Large (10 to 12 years), with height and chest measurements on the size guide to confirm the band.
Is a Lego Ninjago costume good for World Book Day?
Yes. Ninjago is a LEGO character range with its own books and series, and the Basic tunics go on over your child's own clothes, so a school day in one is straightforward; the jumpsuit hoods leave the eyes open for a classroom.
What comes in the pack with a Lego Ninjago costume?
Basic sets: foam tunic, moulded head mask and Lego hands, worn with your child's own top and trousers; the Kai Basic sword is sold separately. Kai Jumpsuit Classic: jumpsuit and Kai hood mask. Lloyd Deluxe: tunic, trousers, mask and hands. Lloyd jumpsuit: jumpsuit and ninja mask. Each listing's includes section confirms its own contents.
Do you sell Lego costumes for adults?
Our Lego range is sized for children only. Grown-ups joining in can pick from our adult ninja costumes instead.
How do I wash a kids Lego costume?
The jumpsuit and deluxe styles are a hand wash (cool water for the jumpsuit), then a flat air dry away from direct heat; never the machine. The Basic tunic listings carry no washing instructions, so check the listing or ask us before wetting the foam.
