The amount of buttons should be on your jacket’s cuffs is not something that is governed by laws or even just general norms.
Four buttons have become standard on the cuffs of every garment in existence, and this practice is considered normal worldwide.
While it used to be the norm for English tailors, today’s Italian and American suits tend to have the most sleeve buttons.
In the 1980s, Italian suits were required to have three-button sleeves as a matter of course. Only the first two closures can be fastened with those.
Compared to the other buttonholes, the final one is a little lengthier. Some people believe that a blazer with two buttons on the sleeves is less formal than one with three or four buttons.
In America, suit coats and other types of blazers were frequently seen with a two-button sleeve in the 1950s and 1960s.
The 1960s fashion of one-button jacket cuffs is marginally more common with Bond than two-button cuffs.
One-button cuffs are viewed by some as being less official than three- and four-button cuffs, similar to how some people view two-button cuffs.
However, more formal jacket cuffs were frequently given one button in the 1960s as well.
To summ all of it up, the most casual is the one buttton sleeve, two buttons, three butons and four buttons, respectively with the last being the most formal type.
