A tall man in a suit with two buttons on his upper body is already very beautiful. A suit jacket with three buttons will make the upper body look too long, which exaggerates the visual sense a bit and is unnecessary. The same is true for vertical stripes, which have an elongated effect and are not recommended for tall people.
If the ratio is super good, the vertical stripes have little effect. If you think the waistline is too long, don't try it.
And the button position on the suit jacket is also very important. If the button position is low and the collar is deep, V will appear more stable and atmospheric visually.
Sleeves are just the opposite of small ones. The younger one should choose a suit with short sleeves and many shirts. Tall people don't have to show too many shirt sleeves, which can avoid the upper body being too long.
