Snugmonster — Baby Monster Costume
Plush spotted fleece with two soft horns on the hood, long sleeves, long legs and a zip that runs the whole way down. A monster, technically — though nobody who meets them is going to be frightened.
The least frightening
monster ever made.
The horns wobble when they walk. The spots go all the way round. And the whole thing is so soft that the first thing anyone does is put a hand on their head, which is not how meeting a monster is supposed to go. That's the product, really — something enormous and terrifying, rendered at knee height and entirely in fleece.

Three details you'll spot
the moment you unfold it.
Horns that stand up
Padded and sewn in, so they hold their shape instead of flopping sideways after ten minutes. They sit above the forehead rather than over the eyes — the silhouette reads from across a room.
Softer than it looks
Thick plush fleece, warm without being stiff or scratchy. It's the difference between a child who settles into a costume and one who spends the evening trying to get out of it.
One zip, done
It opens all the way down, so getting them in takes one pull rather than a wrestling match — and changes don't mean undressing them completely on somebody else's sofa.
Between two sizes?
Take the bigger one.
Sizes are named by age, but children vary enormously at the same age. Every number below is the suit itself, measured flat — so the quickest check is to lay out something they already wear and compare.
| Size | Length | Chest, all round | Shoulder to crotch |
|---|---|---|---|
| 6–12 months | 23.2″ | 24.4″ | 16.7″ |
| 12–18 months | 25.2″ | 25.2″ | 17.7″ |
| 18–24 months | 27.2″ | 26.0″ | 18.7″ |
| 2–3 years | 29.1″ | 26.8″ | 19.7″ |
| 3–4 years | 31.1″ | 27.6″ | 20.7″ |
| 4–5 years | 33.1″ | 28.4″ | 21.7″ |
These are the suit's own measurements, laid flat — not your child's. Length runs from the shoulder seam to the hem, and chest is the full way round. If they're near the top of an age range, take the next size up: there's no such thing as a child who got smaller between ordering and Halloween, and thick fleece is far more forgiving roomy than snug.
Our safety and quality promise
- ✓It's a costume, not sleepwear. Made for supervised, awake wear — play, photos, trick-or-treating. Please take it off, hood included, before bed.
- ✓No small parts. The horns, spots and face are stitched soft fabric, not glued-on plastic pieces.
- ✓Nothing around the neck. No drawstrings, no ties, no cords anywhere on the garment.
- ✓Machine washable. Cold gentle cycle, tumble low or hang to dry. It will need it.
Order by October 15.
Every order ships tracked and insured. Leave it much past mid-October and you're relying on the courier — and there's no good way to explain that to a four-year-old.
What parents ask
before they buy.
Can they sleep in it?
No. It's a costume for supervised, awake wear — take it off before naps and bedtime and follow normal safe-sleep guidance. We'd rather say that plainly than let you find out from the care label.
Which size do I pick?
Measure, don't guess. Take a sleepsuit or romper they already wear, lay it flat, and measure from the shoulder seam to the hem — then match that against the Length column. If you land between two sizes, take the bigger one: it's a loose plush suit meant to go over clothes.
What if I order the wrong size?
Free exchange, both directions. Message us and we'll send a label and the right size at no cost.
What do they wear underneath?
A bodysuit or a thin long-sleeve top is plenty — this is a full plush suit, so it does the warming. That also means it can run hot at an indoor party: dress them lightly under it and unzip the top if they get pink-cheeked.
How do I wash it?
Cold gentle cycle, tumble dry low or hang to dry. Don't iron the horns.
When will it arrive?
Every order ships tracked and insured, and you'll get the number as soon as it leaves. Order by October 15 and it will be with you in time for the 31st.
Try it on. Then decide.
Thirty days, no questions. If the size is wrong we swap it free. If it isn't what you hoped for, we send a label and refund you in full. Costume season is stressful enough.
Tag us — we'd love to see them in it

These are the suit's measurements laid flat, not your child's. Compare them against something they already wear — and between two sizes, take the bigger one.
