Concert attire varies depending on the city and the venue, but semi-formal is always a safe option. For classical and symphony concerts, or recitals, semi-formal or business attire is appropriate. For opening nights or holiday events, formal wear or semi-formal wear with elegant or upscale accessories better marks the occasion.
At pop, rock, hip-hop or country concerts, any comfortable clothing is acceptable. Most concert goers choose to wear clothing that expresses their own personal sense of style. If the concert includes dancing or standing, comfortable footwear is essential. Regardless of the music genre, concertgoers should not wear hats to avoid blocking the views of others.
