Kids Costumes

Boys costumes

Our boys picks start with a plush monkey onesie in baby sizes and go up to a samurai robe for ages 4 to 14.

A full-length black robe with red edging and a yellow belt gives the Boys Samurai Costume its warrior look. The belt adjusts at the waist, and it comes in four sizes for ages 4 to 14.

Spell-casters get a hooded black robe with wide sleeves and a magic wand in the Boys Wizard Cape Costume with Wand. It is cut to layer over everyday school clothes, sized for ages 4 to 14.

The Boys Monkey Onesie Costume starts at baby sizes. It is a soft plush onesie with a hood, 3D ears, a detachable tail, and anti-slip foot covers, and a plush banana comes with it. Four sizes run from baby through small child.

Girls costumes

Each girls pick covers a different theme: a fairy-tale heroine, a pink striped cat, and a 1950s poodle dress.

Fairy-tale fans can choose the Girls Little Red Riding Hood Costume, a red and white dress with an attached checked apron front and a red hooded cape, in four sizes for ages 4 to 14.

Pink and purple stripes run through the Girls Pink Striped Cat Costume. The set has a glitter-trim dress with an elastic waistband, matching leggings, a fuzzy ear headband, a detachable tail, arm warmers, and fingerless gloves, in four sizes for ages 4 to 14.

The Girls 50s Rock 'n' Roll Poodle Dress Costume takes its dance-hall look from a red poodle-print skirt, a black bodice, a polka dot collar, and a red satin necktie scarf. It comes in four sizes from small to extra large.

Halloween, World Book Day, and Christmas

For scarier looks, browse kids Halloween costumes. The wizard robe and Little Red Riding Hood dress suit book-character dress-up days, and kids World Book Day costumes and kids Christmas costumes cover those dates. To browse by theme instead, try kids fairy tale costumes, kids animal costumes, or kids ninja costumes. The full range by age is on our main kids costumes page, and grown-ups can browse mens costumes and womens costumes.

Sizing boys and girls costumes

Boys and girls in a product title describe the styling, and sizing goes by age and build, so a child can choose by look rather than by label. The samurai, wizard, and Little Red Riding Hood costumes run small for ages 4 to 6, medium for 7 to 9, large for 10 to 12, and extra large for 12 to 14, the striped cat costume covers ages 4 to 14 in four sizes, and the monkey onesie starts at baby sizes. Every product page carries its own size guidance, and the size guide has the full measurements. All of our kids' products are safety tested by accredited labs.
