The young model bared it all for her latest spread — and her totally toned abs and waif-like frame have everyone talking about her pin-thin figure. Fresh off her first walk down the Victoria’s Secret runway, you can now catch 19-year-old Karlie Kloss totally naked in the December issue of Vogue Italia, shot by Steven Meisel. Over the course of the last year, the model is definitely embracing more grown-up roles and she also definitely seems to be showing off a thinner frame. While I was shocked to find out that Karlie was so muscular, many think her thin frame is alarming. Karlie is one of the most talented models around and she has always had a fantastic bod — but I definitely think she has dropped some weight, and it’s totally unnecessary! From her killer model walk to her gorgeous face and endless legs, she definitely never needed to shed a pound to get noticed. Check out the latest shoot and weigh in on the great weight debate below!
