What do you mean by dressed like this? What clothes to wear

Men generally refer to suits, including single-breasted and double-breasted ones. My friends in front have made it very clear, so I won't repeat it.

Let me just talk about women's formal clothes.

There are two kinds of formal dresses for women, one is a suit, that is, a suit above and pants below. It is also this type to change pants into suits and skirts. Generally, this kind of clothes are mostly worn by professional women.

The other is a dress, which is usually worn at parties, large dances and award ceremonies (because of the entertainment circle, women used to wear suits, trousers or skirts at the original award ceremony, but it was gradually replaced by dresses).
