I would take it as a given that this would be restricted to UK-only delivery to avoid trading on the WMF's toes, or that of any other chapters.
"Wikipedia" t-shirts should probably be UK-only. "Wikimedia UK" t-shirts may as well be global, although I'm not sure many people outside the UK would want one (unless they buy it at a WMUK event as a momento, I guess, but that would be selling it in the UK, so is irrelevant).
