The diagram on the left maps the 'seventy or more' buttons punctuating the correctly dressed gentleman of the early 20th century (rather than the average Joe), and that on the right does a similar job for the placement of pockets. A shame cargo pants weren't around at the time.
These have provided inspiration for my own up-to-date version, below, which features locations for body piercing. It's deliberately rather unspecific, as I'm rather squeamish about some of the regions available for this variety of decoration. Suggestions welcome.
