Do i need a website to sell at amazon?

I want to sell of some of my new unwanted clothing tho. but i didn't get approved after sending a approval request. they said that " Ensure you have your own website with functional shopping cart. Where we can review your product images to meet our image standards and requirements"
what does this mean??

I just don't think Amazon is right for one of a kind items like that, they want dealers of new products stocked in some quantity.

I would think Ebay or even Craigslist.org local classified ad might be more suitable.

Any local consignment stores?

I'm not sure about the site requirement, but it seems to be a standard procedure, in part to raise the business credibility.
