If you choose the right clothes, you won't feel old-fashioned Maybe it's the way those leaders on TV dress.
First of all, the dress shirt should fit, but it's a pity that the domestic shirt is too big and loose to look good.
Secondly, you should choose a shirt with better texture, and the collar and cuffs should be quite straight.
If you are younger, you can choose a narrow tie, which will look more fashionable.
I suggest you go to the official men's wear network. They specialize in making formal shirts and have many choices.
