Hover to zoomSize guide & how to measure
Pet coats and jumpers are sized mainly by back length, with chest girth as a second check. Back length matters most for coverage.
How to measure
- Back length: measure along the spine from the base of the neck (collar area) to the base of the tail.
- Chest: measure around the widest part of the ribcage, behind the front legs.
- If the two measurements suggest different sizes, choose by back length and allow for the chest.
| Size | Typical back length | Typical chest |
|---|---|---|
| XS | 20–25 cm | 30–40 cm |
| S | 25–32 cm | 38–50 cm |
| M | 32–40 cm | 48–62 cm |
| L | 40–50 cm | 60–76 cm |
| XL | 50–60 cm | 74–92 cm |
Ranges are approximate and vary by style. Always check this product’s Specifications for its exact measurements.

Full description
Full-body costumes work by changing the outline rather than adding a print. Instead of a pattern lying flat on the back, there is structure that alters the shape of the animal, so it reads from across a room and in a badly lit hallway on a wet evening. That is the reason people buy them for parties, and the reason they photograph so much better than a bandana under artificial light.
We know it is a full-body costume, we know the two colours, and we can see the photographs, but there is no fabric description, no size chart and no character name attached to either option. We would rather say so than write a paragraph of invention around a product we cannot describe properly.
- Full-body costume that changes your pet's outline
- Two colour options: yellow or purple
- Reads clearly from a distance and in low light
- Suits parties, walks on the night, and photographs
- No size options are listed, only the two colours
Two things worth knowing. And full-body costumes cover more of the animal than anything else we sell, so watch for overheating, keep sessions to a few minutes, and stop at the first sign your pet has had enough.
Who it's for: owners heading to a party who want a costume that actually reads across a room, and who are relaxed about a listing that tells us less than we would like.

Why we chose it
Structure rather than a flat print, so it changes the outline and reads across a room and in a badly lit hallway. That is why these photograph so much better than a bandana. Stop at the first sign your pet has had enough.
