Men's bodysuit with press studs at the crotch, made of cotton, microfiber or shaping fabric, with short sleeves or sleeveless: a piece that keeps the shirt tucked in and smooths the torso.
A men's bodysuit is a extended body vest, fastened with poppers at the crotch. Its function is clear and technical: it never rides up, which solves two common issues, the shirt or t-shirt coming out of the trousers throughout the day, and the bodysuit creating a bulge at the waist.
There are three main uses. The professional setting first, where a shirt needs to stay perfectly tucked in during a day of meetings or travel. Physical jobs next, where the garment is constantly in motion. And finally, for smoothing, a men's bodysuit made from lightweight compression fabric eliminates creases under a fitted shirt or tailored suit, without the restriction of a separate shapewear.
Models of popper bodysuits open and close like a classic bodysuit, which remains the most practical for daily wear. Models with a sewn crotch, without an opening, are slimmer under clothing as they eliminate the bulk of buttons, but require complete undressing. The choice mainly depends on how often it's used: poppers for daily wear, closed crotch for special occasions where elegance is key.
The men's bodysuit in cotton elastane is suitable for daily wear and is breathable. Microfibre, finer and smoother, disappears under a thin shirt and dries quickly. For size, the length of the torso and chest measurement are what matters, not the waist size: a tall man will often take a size up to prevent the crotch from pulling, just like with a women's bodysuit.
