63577 Clothing Site Marketing

I need to drive traffic to my website ([login to view URL]) and increase orders during the holiday season (Nov 1-Dec 15). I am starting my advertising campaign on Overture and Google this week and we are already optimized in the search engines, so I don't need help with either of those things. Without advertising I am getting 150 sessions per day (according to Urchin 5) and about 3 orders a week. My goal is to at least triple my current sales. I am interested in help with any ethical method to increase traffic and sales, I.E. banner ads, opt-in e-mails, link exchanges or any other ideas.
