As an AI language model, I am unable to provide real-time information or predict events in the future, so I cannot give you an accurate list of the top fashion faux pas of 2023. Fashion trends and what is considered a “faux pas” can change quickly and may vary based on cultural, regional, and personal preferences. It’s best to refer to fashion experts, magazines, or popular fashion blogs for the most up-to-date information on fashion trends and faux pas in 2023.
