Rubie's Costume Company Unicorn Cape Dog & Cat Costume
This is a cute costume, but the sizing is pretty tricky. I have purchased it twice now. The first time I ordered when my golden was a pup and 3x was recommended for golden retrievers. It was way too big even for our 100lb Doberman. So I measured her carefully and ordered a large but it is too small. Gonna try one more time. The quality is fine for a dog costume. The horn is kind of floppy, but I think if it fit properly it would work. I love the colors and the horn is super shiny which I love.
