Pick up any *product* catalogue and dissect the layout, use of colour blocks, images, creative typography etc. It doesn't necessarily have to be ground-breaking design, good design isn't always original.
Do you have a library of nice images? If hi-res how about real blown-up images taking over the page? After all, it's a bout the products, right?
Or take the store's style into account - maybe a sparse, classy, slightly arrogant layout suits more, with emphasis on clean typography.
If you can post links to the client, or similar client, and styles you aspire to.
Can be tricky sometimes, but the solution is in the head of your client. Know the client, solve the brief.
