The antonyms for the word "more designed" are "less designed," "poorly designed," "unplanned," and "unintentional." These antonyms suggest a lack of intentional thought or planning in the design process. Using these types of designs can result in a less polished or cohesive end product. However, it is important to note that these types of designs can still be functional and serve a purpose. Sometimes, a less designed approach can result in a more organic or authentic result. Ultimately, the choice of design style is dependent on the desired outcome and the message the designer is trying to convey.
