I work in advertising, but try not to make it my life. I love writing, art and design - and focus my time on these when I'm not working or hanging out with my family.
Took a quick visit around Marc Jacobs website and was pretty impressed with the overall look and feel (http://www.marcjacobs.com/).
createthe group, who designed the site, has done a good job of showing off their capabilities on their own site. They concentrate only on fashion retail online, with an emphasis on luxury brands.
Surprisingly the fashion industry has been historically behind when it comes to an online presence. Let's hope agencies such as this one put an end to that.
