Tattoos have come to symbolise modern masculinity. As men are spending more time working out their bodies they are drawing attention to their muscles by decorating them. Not a trend I would take permanently, without some serious thought, on the right person it can look incredibly sexy. At the recent Louis Vuitton men's show New York based artist Scott Campbell was recruited by Marc Jacobs (whom he tattoos) to decorate the models. Since his buffed up 'makeover' Marc Jacobs has decorated himself in numerous tattoos. There seems to be a trend for traditional motifs such as swallows and even anchors. It's a kind of retro sexuality. A model at the Alexis Mabille show was decorated with floral tattoos and when Riccardo Tisci, the designer at Givenchy, came out at the end, his leopard print top under his T-shirt looked like a tattoo.
