It's reversible, and the hood can be secured with buttons. There's also a hole for a leash, so you can wear it with a collar or harness underneath. I bought it at a store, but it doesn't fit my dog, so I'm selling it. I only tried it on my dog once at home when I bought it. Back length...31cm Chest...41-47cm Suitable dog breeds...Pugs, Beagles, Miniature Schnauzers, etc.
