When it comes to describing someone who is overly concerned with appearing proper and refined, there are several synonyms that might come to mind. These could include affectedly proper, prissy, fastidious, fussy, or even prim. Each of these terms suggests a certain level of preoccupation with maintaining an image of propriety and good manners, often to the point of being perceived as insincere or contrived. Whether in conversation, behavior, or dress, someone who is described as affectedly proper is typically viewed as being somewhat stilted or formal, with a tendency to prioritize social conventions above authenticity or spontaneity.
