Petalura Calico Cat Shirt. This rainbow watercolor kitty has plenty smile about. For starters, she graces a comfortable oversized tee made of a soft poly/spandex knit. It’s digitally printed in a California studio run by a husband and wife and a small group of creative designers. The generous cut hangs nicely and dips a little bit at each hip, a small detail that flatters virtually every body. Armpit to armpit measures 19 inches.
