Low pr wordpress sites

I have a few wordpress sites, but in particular I have two fashion sites that were doing quite well, but over the past year, things have gone downhill, and I am struggling to get the pr and visitors back up. I would appreciate some honest criticism, on the design and content, and what I could do to improve the sites. Thanks.
