More than a few things going on with the site.
First and foremost, there is almost nothing for Google to catalog. You need text for it to index, and right now, there isnt much on the main page.
However, beyond that, you've chosen xhtml-strict for the main page, yet links off of main dont follow suit, and dont validate. (The pages that actually have text that could be catalog'd!)
Further, for the items you are selling, you give extremely little detail. Spending $4k online is very rare, and to give the potential buyer only *one* page of detail per item, and one popup window is .. rather spartan. A dozen pictures, detailing out the inside stitch work, the trim, the color against neutrals, the quality.. so much could be added.
Also, *zero* pages link to your site in google's index. A quick way to remedy that is to find some good PR sites in the category that sell advertising, and buy some. From there, try to find pages with similar interests that link to pages, and submit to them. I'm talking about community sites with actual people and discussions (like this one), not link spam farms.
Finally, and most importantly, make the site *useful*. Right now, it just sells coats. Thats a one-time affair, and unfortunately, google doesnt give very good placement for sales sites. Instead, add some informative pages on coat maintenance, so you get outside links to your site and content - plus you help your potential buyers.
