On pourrait penser à une offre qui se répéte. "Back to the classics - fourth call".

Unfortunately I have only one paragraph and it is a description of a shirt commercialized by the brand (the grandfather shirt). So I have no context at all for 4th call and the client is not always responsive. But thank you for your help :)

Depends on context Unless I'm just missing something, I'd say it probably depends entirely on your wider context, and the surrounding text.

What is your document about? Why is it listing these 'classics'? Is this a special section devoted to 'Classics'? Why des the text say "back to the Classics"? Has the preceding discussion perhaps in some way diverged from discussing the classic lines? Or is this a marketing slogan, as one might find in say "Back to Basics" etc.?
Is this describing the 4th item in a list? What is the origin of this document: US or GB? If it is US, is '4th call' anything to do with sports jargon, e.g. baseball (I'm thinking of expressions like '1st base' etc.)?

Is there an element of auctions. Auctioneers 'call' a sale 3 times — so could this be the notion of "one last time then!"?

You will probably find the answer is given by the rest of your text, if you can only glean the clues you need...
