From the Knit Picks Website:
This tank top is knit in the round from the bottom up. It features a lace pattern on the front, with an option to use it on the back as well. The hibiscus is evocative of fun summers spent in tropical places. So whether she’s spending the summer in the tropics or just wishes she was, this tank will look great on your girl!
