I’m absolutely in love with this costume and how easy it would be to recreate. You can find this idea for a DIY raining cats and dogs costume via Real Simple and all you need are rain boots, a rain coat, umbrella and a couple of stuffed cat and dog toys to adhere to the umbrella. The rest of the look can be completely up to you and your liking. So simple but super cute!
