Override css for a particular page

Hello all, I am nearly done with a site for a client (using Pages, not blog entries). However, we have one page that needs to be styled differently from the others. I could make all the needed changes if it were possible to override the CSS for this one page. Question: is this possible?

I know that I can create a custom template for this page, but since there’s only the one, that seems a bit of overkill. I know that in some other CMS tools it is possible to add in a CSS class suffix, so I had hoped to find something like that here.

Thanks in advance for any helpful suggestions.
