Size 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.

Material: Cloth

Full description

Halloween photographs are the entire job here, and the design knows it. Horns, dark fabric and a shape that reads as a small demon from across the garden. This is built for the two minutes it takes to get the shot rather than for an evening of wear, and describing it as a photo prop rather than a garment is the honest way round. Anything bought for a costume photograph should be judged on how fast it goes on and how well it photographs, and on both counts it does the job.

It lays over the back and fastens rather than being stepped into, so you are not manoeuvring paws through holes while a dog spins on the spot. Dark fabric photographs best with light behind and slightly to one side, since flat, straight-on flash tends to swallow all the detail in the folds. Set the shot up before the costume goes on and you will need far less of your pet's patience to get a picture worth keeping.

Two things worth knowing. Costumes come in fancy-dress sizing rather than clothing sizing, so measure your pet's chest girth just behind the front legs and compare it with the size guide instead of ordering by breed. And this is a prop, not clothing. Put it on for the photographs, stay with your pet the whole time, and take it off straight afterwards.

Who it's for: Owners after a quick, striking Halloween photograph with a pet who will tolerate a costume for a few minutes.
