The short version
Adults can improvise on the night. Children cannot: a school parade or an organised round happens at a fixed hour, and a costume that does not fit at six o'clock is a costume that does not exist. Buy in the order of who has the earliest deadline, not who is easiest to dress.
Measure the child, not the age on the label
Children's sizing runs on age, and age is a poor proxy for a chest measurement. The number that matters is chest circumference, then height. A costume one size up can be belted; a costume one size down cannot be rescued on the day.
Everything in Halloween as a Family is grouped so that an adult and a child outfit can be chosen in the same register — the mismatch that spoils photographs is usually one comic costume next to one serious one, not a difference of quality.
What children actually tolerate for two hours
Three things end a child's evening early: a mask that restricts breathing, a hood that blocks peripheral vision, and a hem that drags. A full-face mask is fine for photographs and poor for walking. Face paint does the same job for a whole evening without any of the three problems.
Shoes are the other silent failure. A costume that requires specific footwear will be worn with trainers anyway, so it is better to choose something that looks right with the shoes the child already owns.
The dog, who did not ask for this
Pet costumes work when they leave the head, legs and tail free and when they come off in one movement. Two minutes of photographs is the realistic target, not an evening. Anything that fastens under the belly should be checked for tightness with two fingers, and removed the moment the animal starts trying to shed it.
Buy in one go, not in three
The most common failure is not cost, it is timing: three separate orders arriving on three different days, one of which is late. Our bundles exist for that reason — an adult costume and a child costume in the same parcel, chosen to sit in the same register.
Getting ready in the right order
The evening runs better if the child is dressed last, not first. A costume put on an hour early is a costume that has already been spilled on, sat on and complained about. Adults first, house second, child ten minutes before leaving — in that order, every time.
Face paint is the exception: it needs ten minutes to set before anything touches it, so it goes on before the costume, not after. Applied over a collar, it ends up on the collar.
What to check the week before
Three things, and all three fail silently. That the costume actually fastens on the child rather than on the hanger. That whatever is lit still lights — batteries stored in a device over a year corrode. And that the route you plan to walk is one you would walk without a costume, in the dark, with a child who is tired.
The label that tells you how a costume burns
Costume fabric is regulated in the United States, and the rule is more specific than most buyers realise. Under 16 CFR Part 1610, the Standard for the Flammability of Clothing Textiles, fabrics are sorted into three classes by how fast they burn. Class 1 is normal flammability and acceptable for clothing. Class 2 is intermediate and applies only to raised-surface fabrics, to be used with caution. Class 3 is dangerously flammable and may not legally be used in wearing apparel at all.
The standard applies to fabrics and to finished garments, and it was amended by the Consumer Product Safety Commission in October 2023, with the updated version taking effect on 22 April 2024.
What this means when choosing for a family is less about reading labels than about knowing which shapes cause trouble. Loose, trailing and raised-surface materials — capes, long sleeves, fake fur, anything with a nap — are the ones the standard treats with most caution, and they are also the ones that pass nearest to a candle on a doorstep. A cape that stops above the ankle is not a compromise on the costume; it is the difference between brushing a flame and catching it.
