Calvin Klein's ads tend to be two things: sexy and semicontroversial. So when we found out that big names like Justin Bieber scored campaigns, we can't say that we were too surprised. But he's not the only man who brought out the big guns for the iconic fashion house. We'll never forget Mark Wahlberg [1]'s 1992 campaign, and Bella Hadid and Kendall Jenner are the latest ladies to strip down to their skivvies. But before you get too hot and bothered, it's time to reminisce about the much-hyped campaigns of years past. We rounded up some of the illustrious brand's sexiest ads so you can drool — er — decide for yourself. Enjoy, but be warned, these pictures definitely aren't office appropriate!
