Single Vent Suit
When you look at the back of a blazer or jacket, you’ll see a small slit called a vent. A centre vent is one in which the opening is located in the exact middle of the structure. When you put your hands in your pockets, the centre vent of your suit jacket separates slightly, revealing your back. If you don’t want your underarms to get too warm, you should keep the jacket’s central vent closed. It’s a sign of a poorly fitting jacket if the vent opens even when your hands are in your pockets.
Side vents, as the name implies, are slits on the side of the jacket that prevent the fabric from splitting or bunching when you put your hands in your pockets or sit down. The back is always hidden thanks to the large central flap, which also helps you avoid creasing and look trimmer.
An Italian favourite, the no vent suit is the epitome of refined Italian style. The lack of vents, however, makes the jacket more prone to creasing and bunching when you put your hands in your pockets or take a seat. The formal tuxedo is the ideal garment for this cut.
Flat Front Pants
Flat front pants are exactly what they sound like and are a common style of pants for men. To wit, the fabric drapes smoothly in front and provides a form-hugging silhouette. You can achieve a chic and trim look by wearing your flat-front pants at a lower waist. Of course, if you’re carrying extra weight around your middle, you should choose a looser pant cut to hide your beer belly.
Essentially, it’s a less comfortable modern suit with a more streamlined silhouette.
Pants that have pleats in the front have had the fabric folded and stitched into creases before being attached to the waistband. As a result, the middle of this suit is more relaxed, and it should be worn slightly higher on the hips so that it doesn’t flap around. You should get a pair of modern suit pants that fits closely and looks relatively snug, even though pleated pants are more comfortable to wear in general, especially for larger me.
Note how the pleats widen the seam to accommodate your expanding thighs as you sit.
Trousers worn with suits can be hemmed or cuffed, depending on the design. The difference between hemmed and cuffed is that the former has the fabric turned up on the inside, while the latter has it turned up on the outside. You’ll see both hemmed and cuffed pants and shorts, but the former is more common. It’s a good rule of thumb to have flat-front pants hemmed and pleated pants cuffed, but these guidelines aren’t set in stone. However, cuffs are typically included on pleated pants to increase the pants’ overall bulk and smooth out the fabric.
