Suits need to fit well

After the opening up of China, every time period has a name, becoming a symbol of men's taste. But there is no name that can represent the suit he is wearing, it must be a good suit.
You can check if your suit fits according to this standard. After talking about fit for so long, how do we define fit? There are several standards:
From the front, there is no sense of looseness from top to bottom, and at the same time, it should not be too tight to create pulling wrinkles.
The problems exposed by oversized suits include:
1. The suit has no waist and is in a cylindrical shape;
2. The sleeves are too long, covering the cuffs of the shirt (as shown in the top left picture).
The problem reflected by a suit that is too small is:
1. After buttoning up the suit, there is a pulling sensation on the chest, forming obvious radial wrinkles;
2. Sleeves too short, shirt cuffs exposed too much, greater than 1cm
From the back, perfectly outline the curve of the back without wrinkles when standing straight.
An oversized suit will have obvious excess gaps on the back (as shown in the top left image),
A suit that is too small has obvious horizontal wrinkles on the back and a tight feeling on the upper body
From the side view, the sleeves should be as thin as possible and should conform to the natural curvature of the arms. When the arms hang naturally, there should be no wrinkles, and when the hands hang naturally, the shirt should be exposed by about one centimeter.
An oversized suit can cause:
1. There is stacking at the elbow, forming wrinkles;
2. The sleeves are too long and cover the cuffs of the shirt (as shown in the top left picture).
A suit that is too small:
It is tightly stretched on the arm, and there is obvious pulling at the armhole, forming radial wrinkles
