Maintain a professional appearance. Pair ironed trousers or a skirt with a button-down shirt, blouse, or sweater. You may add a blazer or a cardigan for extra warmth. Consider wearing a basic knee-length dress with stockings if you like a single piece. Avoid wearing jeans or T-shirts since they seem too casual. In general, wear clothes that make you feel comfortable and confident. If you feel self-conscious about something, then leave it out of your outfit. For example, if you have tattoos, then wear shirts or dresses that cover them up. If you have scars, then wear outfits that show them off instead of hiding them. Also, keep in mind that the first impression you make with others is very important. So, look your best by wearing appropriate attire for an interview.
