All set for their close-up.
Find the right fit, get to know the costume and plan for your occasion.
Details, sizing & delivery
Uh oh. Your dog's come to life... and they want to play. A striped jumper, blue dungarees, a wild ginger wig and a soft foam toy knife turn your sweetest family member into the creepiest doll in town. It's the costume that makes people scream, then laugh, then ask where you got it.
- Instant horror-movie laughs: the wig, stripes and dungarees make the joke obvious from across the room.
- Made for the camera: perfect for Halloween photos, parties, trick-or-treat doorsteps and "something's not right with the dog" videos.
- Your dog, the star: bring them into the family Halloween photos this year instead of leaving them out.
- Complete set: outfit, adjustable wig and foam toy knife all included, so it's ready to wear straight out of the bag.
Find the right size
Measure around the base of your dog's neck and the widest part of their chest. Pick the size that fits both measurements with room to move. Go by measurements, not breed or weight.
| Size | Neck | Chest |
|---|---|---|
| S | 25–40 | 35–50 |
| M | 30–45 | 45–60 |
| L | 35–50 | 55–70 |
| XL | 40–55 | 65–80 |
Between sizes or not sure? Message us with your dog's measurements and we'll help you choose.
Happy dog, happy photos
Let your dog sniff the costume first, then try it on for a few minutes at home with treats and praise. Use it for short, supervised dress-up sessions and take it off if your dog seems uncomfortable or starts chewing it. The wig and foam knife are decorative, so keep an eye on chewers.
Dress-up only: use a proper collar or harness for walks and never clip a lead to the costume.
Delivery & Halloween timing
UK delivery is included. Orders are prepared and dispatched within 1–3 working days, then shipped with tracking. Most orders arrive 5–10 days after ordering; a small number can take up to around 2 weeks.
Need it for Halloween? We recommend ordering by 17 October. If you need it by a specific date, message us before ordering and we'll confirm delivery timing.
