The word "re-dressed" implies that something has been dressed or clothed again. Therefore, antonyms of the word will be those that suggest the opposite. Some possible antonyms of "re-dressed" could be "undressed," "naked," "bare," "stripped," or "exposed." They all convey a sense of removal or absence of clothing. Alternatively, antonyms of "re-dressed" could be words that suggest that the clothing is old, torn or worn out, such as "tattered," "ragged," "scruffy," "shabby," "worn," or "frayed." These antonyms are useful when wanting to convey that something is in need of new clothing, rather than simply being unclothed.
