Jeans and sports shoes should not be worn in formal workplaces, but trousers and leather shoes should be worn generally. If you are required to wear formal clothes, you should wear a suit (formal clothes rather than casual clothes), shirt and tie; If you just ask not to wear jeans and sneakers, not formal clothes, then you can arrange it like this:

1, shirts and T-shirts can be worn inside, coats and suits can be worn outside, and dark colors are suitable;

2. Wear trousers and leather shoes.

3. The clothing color is mainly dark blue. Try not to choose brown or crimson.

When wearing dark blue pants, you must never wear brown and light shoes, nor light and white socks, which is tasteless. Dark blue trousers with black leather shoes and black or dark blue socks are more suitable.

The hem of a shirt or T-shirt must always be inserted in the waistband, and the sleeves can't be rolled up, which is generally ignored by China people.
