1. Professional: This is the most important factor. Your attire should reflect that you take the interview seriously and are prepared to present yourself as a capable professional.
2. Appropriate: This means considering the company culture and the specific role you're interviewing for. Research the company and try to understand their dress code. A conservative approach is usually best.
3. Comfortable: You want to feel confident and at ease during the interview. Avoid wearing anything that feels restrictive or uncomfortable.
Remember, first impressions matter, and your attire plays a significant role in creating a positive one.
