I took a quick look and I don't see anything that stands out as a problem. My only suggestions are this:
- more photos for each listing, including one with a model wearing the product. I like my shirts long, for example, and would be curious to see how it hangs on a human, rather than a hanger.
- larger sizes. Right now it looks like you have SML but not XL or XXL for plus sizes.
These are my first thoughts but everything else looks great to me. If it makes you feel any better, I have the same issue with my shop. I'm getting some traffic but not selling much. Grrrrrr
