What term describes someone who dresses in a way that is excessively showy and lacking in taste?

The term "bedizen" refers to someone who dresses in a gaudy or over-the-top manner that often lacks taste and discernment. It conveys the idea of ostentation, where the individual's choice of clothing and accessories is intended to attract attention, often resulting in a look that is excessively showy. This word is particularly useful in contexts where someone’s fashion choices are criticized for being flamboyant or garish.

In contrast, the other terms do not relate to clothing or taste in appearance. "Apposite" means appropriate or suitable, "arabesque" refers to an ornamental design or a specific ballet position, and "apotheosis" signifies the elevation to divine status or the highest point of something, none of which connect to the idea of dress and taste in the same manner as "bedizen."
