Eh, it's not-too suggestive for the rating to be questionable.

If the rating of a picture is unsure, then it's questionable.

Questionable is for nudity that does not have any sexual connotations, and is the default for any post. Otherwise a post requires rating:safe for no nudity and rating:explict for any sexual acts.
