To Target's Circo footed sleepers. I went into the store and the biggest size they had at the time were large, so I ordered an xl online. It fit, but I wanted more so I went back to the store and what do you know they had all styles of xl in stock. I contemplated buying one from the woman's section to have a larger fit (they have cute red foxes, blue sharks, sock monkey etc) on sale for $20. After not being able to decide I went with two more pairs of the Circo ($12.99 each). I am thinking of going back each month and buying one until I have the entire line. There just so cute and keep my poorly circulated feet nice and warm, not to mention I find them sooo comfortable. Can you ever have too many sleepers?
