Another idea is to join some forums relating to your website - e.g. women's health and beauty sites or fashion forums. There you can discuss the latest trends for lingerie and your own personal tastes. In your signature you can often put a link to your website which people may follow if they found your comments helpful. Make sure you only write worthwhile posts though as spammy comments could have your account deleted and could also turn people away from visiting your site.
I hope this helps and good luck :)
