This past weekend was ridiculous nice out, even more so if you were in New York and to cool down from the incredible heat everyone hung out in the water. From roof top pools, to cottage dock lounging, the weekend, and every weekend until September is all about lounging in the water. Which means it’s time to get a new bathing-suit and who better to hook you up then Calvin Klein. CK has released their Spring/Summer 2012 Swimwear Campaign featuring models Vladimir Ivanov and Lily Donaldson shot by Sebastian Kim and styled by George Cortina. Need a new suit?
