Styling Rule Of Buttons In Slim Fit Suiting

In slim fit suiting, the styling rule of buttons is that the top button of your jacket or blazer should fit like a glove. A hidden stitch holds it together on both sides, which makes it easy to break in at waist level without any need for alteration.

Use images below as reference about the different button options in slim fit suiting:

One Button Slim Fit 

Button Slim fit jacket gives the slimmest look because it’s low cut. There are no buttons on the shirt cuff of your suit. One Button Suits are made for tall men. This is very popular among tall people because they have to bend down to reach for their hands in their pockets.

One Button's slim-fit styling rule is that the top button of your jacket or blazer should be fastened. Unlike a single-breasted jacket, where there is at least one buttonhole on the lapel facing, it can only be fastened to ensure that the look remains unbroken.

Two Button Slim Fit suit

The two buttons' slim-fit rule is that the top button is fastened while the bottom button below is left open. It gives you a casual look and is perfect for social gatherings, parties, and festive events.

All men with broad shoulders look good in the two-button because it’s comparatively stronger. Persistent nips and tucks are needed to tighten the fabric throughout the chest, stomach, arms, and waist area.

The proper cutting style of jacket can do wonders by adding more texture around your shoulder line, which adds definition in broad men.

Three-Button Slim Fit suit

The three-button slim-fit is a bit extended than the two-button and it suits men who love to add more style statements. It offers you comfort while giving you a formal look. Its styling rule is that the top button of your jacket's body or blazer should be fastened, whereas the middle button on both sides should be left open.

A three-button jacket is not something to opt for if you have an athletic build. Its excess fabric gives the feeling of larger than life, so it’s suitable for men with a thin or average build.
