I saw this kitty [with a bow-tie!] shirt a couple of days ago online and fell in love. How could you resist it?! It's by a company called Brat & Suzie and they have such a funky range of clothes. The kitty also comes on a vest style top as well as a pink tshirt. Perhaps you'd prefer a Pirate Cat crop tshirt instead?
Brat & Suzie are a British company and are a collaboration between Designer Polly Vickery and Illustrator Louise Boulter. They create such unique original designs that you're bound to find something you fall in love with instantly! If you're into the crop style but not into kitties they also have countless other animal illustrations including the Owl Doll which features 4 owl matryoshka [or nesting] dolls. I think, personally, this is my favourite design.
