This picture is most certainly not "Safe". Now perhaps this mistake happened out of sheer force of habit, clicking the "safe" button to get the thing uploaded, but do try to watch your ratings in the future. Err on the side of caution, because the Safe ratings appear on Safebooru. This has an extremely high amount of nudity, so it's most certainly Questionable.

From Howto:rate:

Image ratings help users organize and search through the various levels of explicit content contained on Danbooru. It's very important to rate your uploads properly. By doing so you help ensure that searches continue to return accurate results.

Danbooru has three ratings: Rating:Safe, Rating:Questionable, and Rating:Explicit. Broadly speaking, these categories are:

• Rating:Explicit: For pornography — images containing explicit sex, gratuitously exposed genitals, or that are otherwise pornographic.
• Rating:Questionable: For images that may contain some non-explicit nudity or sexual content, but that aren't quite pornographic.
• Rating:Safe: For everything else. Note that rating:safe does not mean safe for work and may still include "sexy" images containing cleavage, panty shots, skimpy bikinis, and so on.

Do note that while Safe pictures MAY have cleavage, that's more or less so that a picture that has only a little tiny bit won't be disqualified on principle, like post #2834905. A picture that focuses on the sexy aspects is more than likely Questionable.
