Good thinkin', man!

My suggestions:
1) maybe larger or enlargeable images of the different styles of the jackets (for their cuffs, ie the line drawings) for those not too familiar or first time buyers etc.

2) Just a detail, but I personally get kinda picky about the style of epaulettes, ie braided vs flat; don't know if this requires more elaboration etc?

3) From a technical/web user interface standpoint, I would HIGHLY recommend having your links (eg thumbnails and fabric selection) open in a new tab or pop-up window so that the user is not navigated away from the main order page. It can be a frustration to the user especially if they don't realise what has happened and then have to figure out how to get back to the correct page.

Aye,
Wesley
