When describing something as "overelegant," it may sound like it has too much effort put into its appearance, making it appear unnecessary and almost fake. To describe something in a similar manner, you might consider using words such as ostentatious, flamboyant, gaudy, showy, or even show-offish. These synonyms may indicate that something is trying too hard to impress or that it has gone beyond the simple elegance it was aiming for. Other words that may convey an excess of elegance include flowery, ornate, over-decorated, or overwrought. Keep in mind that these words all have slightly different connotations, so choose the word that best fits the context in which you wish to use it.
