As an intern, how to dress up to look mature without losing temperament?

First: interns should not dress too high-end. It's too high. If you look like a boss, you will be in trouble. Second: interns should not dress lightly, but should show the rigor that a professional should have. Third: color matching should be refreshing, and clothes must be neat. Accessories should not be too complicated. Don't make it look like a Christmas tree from a distance, but like a grocery store from a distance. Fourth: respect your gender. Boys give you this advice: clothing plan A: crisp light blue jeans, hair must be washed clean, don't leave long hair. Wear a white T-shirt made of cotton. If it is hot, wear short sleeves. If it is cold, wear long sleeves. Never wear long sleeves with cuffs. If you are short, wear sneakers with bulges inside. If you are not short, please choose flat shoes instead of leather shoes. You can also wear business casual shoes. Pay attention to the color difference between socks and clothes. Give people a fresh and clean feeling, that is, without losing the taste of students, but also give people a fresh feeling, new colleagues will like you more. Clothing scheme B: dark blue or black suit pants, trousers, white shirt and leather shoes. It must be clean and tidy. You can put a thin casual coat on your arm. Pay special attention to the style of belt and the color of socks. It is recommended to choose a business belt, socks and shoes and trousers. Also pay attention to the length of pants, too long and untidy, too short as if they were borrowed. It is recommended to stand up straight and don't show your socks. You must choose dress shoes for leather shoes, because you are wearing dress pants. All the plans I gave you were neutral. Neither young nor conservative. Hehe, maybe you have a better match.
