How to measure
- Neck: wrap a soft tape where the collar sits. Add one finger of room.
- Length: from the base of the neck down the chest to just before the front legs meet the belly. The costume length is the front panel, not the back.
- Between sizes? Go one size up. Tighter is worse than looser.
Measurements can vary by 0.5 to 1 in (1 to 3 cm). Still unsure? Email support@costumepup.com with your pup's breed, weight and neck size and we will pick for you.
