Note
The short adjective takes the -est ending rather than a phrase with most, so plainest is the natural form and most plain is the marked one. The superlative reaches across the several meanings of plain: the plainest dress has the least ornament, the plainest dish the fewest extras, and the plainest explanation is the one most readily understood. Context, not form, tells you which is meant.
