The background can either help enhance the design or distract from it. Avoid clutter and too many objects in the background, and make sure that the backdrop you chose is on theme with the garment / accessory that you are photographing.
It’s a good idea to have at least one of your shots depicting the full item, as well as a close-up of the stitching or colour-work details.
A bird’s eye view / flat lay angle (shooting directly from above) is another great way to show off an item.
