This is an Infant Shrimp Costume, but in this case I used it for my dog. It is a size 12-18 months for babies, but it fit my 9-year-old, 17 lb. Shih Tzu perfect! I thought this was of my most clever ideas. In true Beetlejuice fashion, we had to include the shrimp from the famous "Day-O" (Banana Song) scene. Although in the movie, the shrimp wasn't intended to look this cute! Either baby or dog, your family member will stand out in this adorable costume! Worn once on Halloween for a very short time. Cleaned & disinfected✨ Chest- 25.5" Total Length- 33"
