How does one go about specifying boob size with more granularity? Medium breasts gives me this size which is a bit larger than I am looking for. Small gives me more like this.

Both of these sizes work for these characters in particular, but I was looking for something in the middle for another character. Is there a medium small or some other descriptor I can use in my prompts?
