This is a fluffy penguin dog costume. It was worn by a French Bulldog, but it's not specifically for Frenchies, so I think a medium-sized dog can wear it. It looks incredibly cute when worn! I fell in love with it at a market and bought it, but I can't wear it anymore because I've gained weight, so I'm selling it. Please forgive any errors as these are amateur measurements. Neck: 41cm Chest: 58cm Length from neck to tail: 36cm (It looked like it was trailing behind the French Bulldog.) It's been worn 2-3 times, but please be sure to check the photos for the condition.
