The word "most arrayed" denotes someone or something that is well-organized or well-dressed. The antonyms or opposites of this term are those that represent a lack of order or arrangement, such as disheveled, messy, or cluttered. If a person is not most arrayed, they could be described as unkempt, disordered, or untidy. Similarly, a disorganized environment could be referred to as chaotic, jumbled, or messy. In contrast to "most arrayed," these antonyms suggest a lack of preparation, attention to detail, or effort in presenting oneself or one's surroundings.
