Twelve children's Halloween costumes you can still order in October, with the safety and sizing checks that matter and how to be sure the box arrives.

Researched and written by the vinymart.com editors. How we choose gifts

Halloween falls on a Saturday this year, so many children will be in costume from a morning party until the last doorbell at night. That makes comfort and safety matter as much as how the costume looks.

If the costume is not sorted yet, there is still time. What catches parents out in October is not choice but delivery, so the first rule is simple: read the arrival date on the product page, not the listing title.

What to check before you order

  • Arrival date. Go by the date shown at checkout and leave a margin of at least three days.
  • Flame resistance. Look for a label that says flame resistant. Avoid long trailing fabric and wide sleeves near candles and lanterns.
  • Fit and length. Costumes run small. Size up so it fits over a warm layer, and hem anything that reaches the floor.
  • Vision. Masks narrow a child’s field of view. Face paint or a hat is safer for crossing roads.
  • Visibility. Dark costumes need reflective tape or something that glows.

Price guide: $ is under $25, $$ is $25 to $75. See how we choose for our method.

12 Halloween costume ideas for kids

An inflatable dinosaur costume

Best for: The child who wants to be noticed$$

A small battery fan inflates the suit into a waddling T-Rex taller than the child inside it. Nothing gets a bigger reaction on the street. It is roomy enough for warm clothes underneath, though sitting down in it is awkward.

What to check: The height range in the listing and the battery type for the fan. Pack spares.

An astronaut jumpsuit

Best for: The space fan$$

A flight suit with mission patches is comfortable for a full day and has no mask to restrict vision. It also goes straight into the dressing-up box and gets worn for months afterwards.

What to check: A front zip the child can manage alone, which matters for bathroom breaks.

A classic witch dress and hat

Best for: A classic that always works$

A black dress, a pointed hat and a broom are instantly recognisable and easy to layer over leggings and a long-sleeved top. The hat replaces a mask, which keeps her vision clear.

What to check: Hem length. A dress that brushes the ground is a trip hazard on steps.

A glow-in-the-dark skeleton suit

Best for: Trick-or-treating after dark$

The printed bones glow once the light fades, which children love and which makes them easier to spot. Many versions are soft cotton and double as pyjamas, so the cost is spread across far more than one night.

What to check: Whether it is a one-piece or a two-piece set; two pieces are easier for younger children.

A superhero costume

Best for: The one who never takes it off$$

Whichever hero is the current favourite, a padded suit will be worn for months of dressing up afterwards, so the cost per wear is low. Padded muscle versions are warmer, which helps on a cold evening.

What to check: A mask with wide eye openings, or swap it for face paint when walking outside.

A fleece animal onesie

Best for: Cold evenings and children who hate masks$

Unicorn, shark, dinosaur or bear: a fleece onesie is warm, soft and needs nothing else. It is the least fussy costume there is and the best choice for a child who finds masks and face paint uncomfortable.

What to check: Feet. Open ankles with ordinary shoes are safer outdoors than built-in slipper feet.

A firefighter outfit

Best for: The helper$$

A jacket, a helmet and a few accessories suit both boys and girls and go straight into the dressing-up box afterwards. The loose jacket fits easily over a jumper.

What to check: Reflective stripes on the jacket, which look right and help with visibility.

A princess dress

Best for: The one with a favourite film$$

Choose the character she actually loves rather than the prettiest dress. A cardigan or long-sleeved top in a matching colour underneath keeps it warm outdoors without spoiling the look.

What to check: A soft lining. Scratchy seams and netting are the most common complaint about these dresses.

A pumpkin costume for toddlers

Best for: A first Halloween$

A soft, round pumpkin body over everyday clothes goes on a wriggling toddler in seconds and photographs beautifully. Choose one with a wide neck opening and no hood that can slip over the eyes.

What to check: No small detachable parts. Anything that can come off is a choking risk for under-threes.

A ninja costume

Best for: The one who cannot sit still$

Lightweight, easy to move in and comfortable over warm clothes, a ninja outfit suits a child who wants to run from door to door. Leave toy weapons soft and short.

What to check: Add reflective tape or a glow bracelet. An all-black costume is nearly invisible to drivers.

A water-based face paint kit

Best for: The last-minute backup$

With face paint and clothes you already own you can make a cat, a tiger, a zombie or a vampire in ten minutes. It also replaces a mask on any costume, which is the safer choice for walking after dark.

What to check: Water-based and labelled for use on skin. Test a small patch on the arm the day before.

A light-up treat bucket and glow sticks

Best for: Being seen in the dark$

A glowing bucket and a few glow-stick bracelets make any costume visible to drivers. That matters more than the costume itself, and children treat the glow as part of the fun.

What to check: Battery cover secured with a screw if younger siblings are around.

If the costume does not arrive

Use the backup. A black outfit with painted whiskers is a cat. An old white shirt with a little red paint is a zombie. A striped top and an eye patch is a pirate. Each takes minutes, and children care far more about going out than about what the costume cost.

Common questions

How late can I order a Halloween costume?

It depends on the item and your address. Go by the delivery date shown at checkout, and choose a date at least three days before October 31 so there is time to exchange a wrong size.

What size Halloween costume should I buy for my child?

Buy one size up from the child’s usual size. Costumes run small, and the extra room fits a warm layer underneath. Shorten any hem that reaches the ground.

Are Halloween masks safe for children?

Masks can narrow a child’s field of view, which is a risk near roads. Face paint or a hat is the safer choice for walking outside, and a mask can be kept for photographs and parties.

How do I make a dark costume safer at night?

Add reflective tape to the costume and treat bag, give the child a glow stick or a small torch, and choose light-coloured accessories. Drivers see movement and light long before they see a dark costume.
