Spooky, but make it flattering

Our Halloween pet costumes are made for scene-stealing dogs, adventurous cats, and nothing that takes itself too seriously. Soft linings, adjustable straps, and eyes and ears left clear.

Before you buy

Getting the size right

Read all FAQs
How do I choose the right size?

Go by measurements rather than your pet's breed or weight. Every product page lists chest, neck and back length for each size.

What if my pet is between sizes?

Size up. A slightly loose costume is comfortable; a tight one gets removed in about four seconds.

Do you make costumes for cats?

Yes. Anything marked as cat-friendly is lighter, has no head covering and uses breakaway fastenings.

How long does shipping take?

Orders are dispatched with tracking. Delivery estimates are shown at checkout before you pay.
