A onesie is a one-piece garment typically worn by infants and young children. It covers the torso and often includes snaps at the bottom for easy diaper changes. Onesies are made from soft, comfortable materials like cotton, making them ideal for everyday wear. They come in various colors, patterns, and designs, often featuring fun prints or characters. In addition to baby onesies, there are also adult versions known as adult onesies or jumpsuits. These garments are popular for loungewear and sleepwear, providing a cozy and relaxed fit. Adult onesies often feature hoods and pockets, making them both functional and stylish.
