The suffix -esque, similar to the suffix -like, means in a manner of or resembling. It is a living suffix, so we can attach it to virtually any English noun without using a hyphen.
Examples
Since the rise of software spell-check, which erroneously marks many -esque coinages as incorrect, writers have grown timid about attaching -esque without the hyphen. For example, the hyphen is not technically needed in any of these cases:

But other writers are not so timid about adding the suffix to words—for example:
