Free size is the phrase to pay attention to on this one. There is a single size and no chart standing behind it, which is fine on a scalloped cape that hangs from the shoulders and would look much the same on a whippet as on a house cat, and considerably less fine if you are shopping for a large dog. It is cut generously and it drapes. That is the whole of the fit, honestly described.

The shape does the work here: the edge is cut into scalloped bat wings, so it reads as a costume from across a room without anything being strapped to the animal's legs or wrapped around the chest. It arrives as a two-piece in red or purple, cloak and matching hat, and the hat is genuinely optional. Plenty of pets will accept the cape and refuse the hat outright, and the cape on its own still does the job.

• Cloak with scalloped bat-wing edging
• Supplied with a matching hat
• Red or purple
• One free size
• Drapes from the shoulders, with nothing around the legs

On sizing. One free size means exactly what it says: no chart, no measurements, and no way for us to promise it suits a large or giant breed. Treat it as cat to small-dog sizing unless you have heard otherwise from us directly. Like anything worn, it is for short supervised periods and comes off before your pet is left on their own.

Who it's for: cats and small dogs at Halloween, where a cape and a hat do more than a full outfit ever manages.
