Brand new, only taken out of the package to try it on my shih tzu and to take the pics for this post. I didn’t gauge the measurements correctly - my shih tzu is large for his breed and was too broad across the chest. We ended up ordering a large but didn’t have time to return the medium as they only gave 3 days to return. I have posted a pic of my pup wearing the large so that you can see how the costume should fit if it is sized correctly.
