CK's birthday celebrations continue

Calvin Klein Underwear is 25 years old this year and they haven't stinted on the celebrations. It all kicked off with a star-studded bash at New York Fashion Week, and now here's some pics from the latest leg of the international Calvin-fest: models in a box wearing the anniversary Steel collection. Went down a storm in Hong Kong, as you can see. Find the collection in the UK; in the US.
