1. Symmetrical facial features
2. Clear and smooth skin
3. Well-groomed appearance (e.g., well-styled hair, trimmed beard, etc.)
4. Confidence and good posture
5. Height and a toned physique
6. Charisma and a charming personality
7. Good hygiene and pleasant body odour
8. Fashion sense and style
9. A captivating smile and friendly demeanor
