Prince and Princess Costumes for Kids and Adults: Seven Royal Looks by Budget

Our favorite prince costume for kids is the Boys Fairytale Prince Charming Costume: a royal blue jacket with gold detailing and red epaulettes, a gold sash, and a black belt, in five sizes from 3-4 to 12-14 years, at $38.95. Add a crown or a cape and the look is done. For grown-ups, the picks in this guide start at $37.95.

Princess is the third most popular children's costume of Halloween 2026, with 2.2 million kids, according to the National Retail Federation. Adults are in the picture too: on prince searches that named no character or celebrity, 32% of the U.S. Google web-search impressions our site earned between September 10 and October 24, 2026, came from searches naming men or adults. Every pick sits in our fairy-tale costumes range; our fairy-tale costumes guide covers the rest of the storybook cast.

How much does a prince or princess costume cost?

Our prince and princess costumes run from $30.95 for a kids king set to $72.95 for a women's princess dress, and every kids pick here costs under $50. Prices below are at the time of writing.

Every costume goes through over 30 measurement checks. All of our kids' products are safety tested by accredited labs.

Which prince costumes cost under $40?

Four royal looks cost under $40: a kids king, two kids princes, and a men's Arabian-style prince. Each kids pick pairs with an adult accessory for the grown-up.

The king set with the crown in the pack

The Boys Red Royal King Costume with Cloak is the lowest-priced look in this guide, at $30.95: a red velvet-feel cape with faux ermine trim, a blue tunic top with gold-style accents, and a soft gold crown. Pants are not included; dark pants or leggings work. Pair it with our Adult Royal King Crown, gold and purple with a foam lining, and a parent makes it two kings.

The classic storybook prince in royal blue

The Boys Fairytale Prince Charming Costume has a royal blue jacket with gold detailing, decorative buttons, a detailed collar, and red epaulettes, a gold fabric sash across the chest, and a black belt. The fabric is 100% lightweight polyester with a smooth lining. Add black pants and dress shoes. Hand our Royal Sceptre to the grown-up king beside him: its sections screw together, so the length adjusts.

The white-jacket prince with pants in the pack

The Boys Fairytale Prince Costume is our storybook prince with pants included: a jacket, pants, and a belt, pictured in white and red with gold trim, at $39.95. The elastic waist and center-front hook and loop fastening get it on fast before a party. For a parent, add our Gold Foam King Crown: nine points and an adjustable hook and loop strap, sized for ages 14 and up.

The Arabian-nights prince for grown-ups

The Men's Arabian Rogue Prince Costume packs a cream long-sleeve tunic top, a purple vest with decorative trim, a red waist sash, relaxed-fit pants with an elastic waistband, and a hat. We size it by chest and height, and the sash adjusts around the torso. Pair it with our Adult Pirate Cutlass Sword, a 27-inch plastic prop; its product page suggests tucking it into a belt or sash, and this costume has the sash.

For the storybook look in adult sizes, see our Men's Fairytale Prince Costume; adult kings have their own king costume guide.

Which prince and princess costumes cost $40 and up?

Three looks cost $44.95 to $72.95: a girls medieval princess, a boys Arabian prince, and a women's princess dress. Each one has a crown, a hat, or a wig in the pack.

The medieval princess, crown included

The Girls Medieval Princess Costume is a pink velvet-look gown with gold embroidery and bell sleeves, a belt, and a matching crown. The gown is designed for true-to-size comfort in a non-stretch velour, so pick the size from the size guide before you order. Pair it with our Adult Collapsible Crown Hat, red with a faux fur spotted brim, for the grown-up who walks her in.

The five-piece Arabian prince for boys

The Boys Arabian Prince Costume comes in five pieces: a cream top, cream pants, a purple vest, a red sash belt, and a fez-style hat. The pants have an elastic waistband and the fabric gives a little within each size. Boots are not included. Match a parent in the men's version above, or pair it with our Adult Collapsible King Crown Hat, purple with faux fur trim, for the grown-up beside him.

The purple princess dress with a long blonde wig

The Women's Purple Princess Dress Costume is a purple dress with a fitted lace-up bodice, puff sleeves, and flowing skirt panels, with a long blonde wig, at $72.95. The bodice is fitted, so measure against the size guide first. No crown comes in the pack; our Gold Medieval Queen Crown adds one, with faux gemstones and an adjustable elastic strap, for $13.95.

How do you make a prince costume look royal?

A crown, a sash worn diagonally across the chest, and a cape with white fur-look trim are a great way to make a prince costume look royal. The sash comes straight from real royal dress: the Royal Household's notes on a 2011 royal wedding uniform describe its blue Order of the Garter sash as worn from left shoulder to right side.

• The crown: our Adult Royal King Crown page says to let it rest on top of the head rather than pull it down low. The kids king set and the girls medieval princess each come with one.
• The sash: left shoulder across to the right side. The royal blue prince set's gold sash already drapes diagonally across the chest.
• The cape: the king set's white spotted faux ermine trim borrows from the fur-trimmed robes of storybook kings.
• Gloves and shoes: no prince pack here includes them, so add white gloves and polished black shoes or boots.
• Props for kids stay short: the American Academy of Pediatrics' Halloween safety tips advise against sharp or long swords, canes, and sticks as a costume accessory, so the sceptre and the cutlass go to the grown-ups here.

How do you match siblings or a whole family as royalty?

Pick one style and split the roles: a king and a prince, a prince and a princess, or a parent and child in the same Arabian-nights look. A royal court at a birthday party, a school play, or on Halloween gives every child a part to play.

• Father and son, Arabian nights: the Men's Arabian Rogue Prince Costume and the Boys Arabian Prince Costume share the cream, the purple vest, and the red sash. Think Arabian Nights, the story collection Britannica lists as The Thousand and One Nights; our Arabian nights costume guide goes further.
• Two brothers, a king and a prince: the Boys Red Royal King Costume with Cloak beside the Boys Fairytale Prince Charming Costume, red and gold next to royal blue and gold.
• Brother and sister, prince and princess: the Boys Fairytale Prince Costume with the Girls Medieval Princess Costume, a storybook prince beside a princess in pink and gold.
• Parents as the king and queen: any kids pick with an adult crown from the pairings above.

Younger royals are in our kids fairy-tale costumes.

What size prince or princess costume does my child need?

Our kids' royal costumes are sized in age bands; every kids pick here covers 4-6, 7-9, and 10-12 years. The ends of the range differ:

• Boys Fairytale Prince Charming Costume: five sizes, 3-4 up to 12-14 years; between two, the product page says go up.
• Boys Fairytale Prince Costume: three sizes, S, M, and L, for 4 to 12 years.
• Boys Red Royal King Costume with Cloak: three sizes for ages 4 to 12; pants not included.
• Boys Arabian Prince Costume: four sizes, 3-4 up to 10-12 years.
• Girls Medieval Princess Costume: five sizes, 3-4 up to 12-14 years. Measure against the size guide before you pick.

Grown-ups size differently: the women's dress comes in S to XXL, and the men's Arabian prince in M to 3XL by chest and height. Kids the same age vary in build, so check the size guide on each product page. A long gown's hem should clear the shoes: the AAP says costumes should be short enough to prevent tripping.
