Sleeve styles refer to the various designs and cuts of sleeves on garments, influencing both aesthetics and functionality. Common styles include set-in sleeves, which are sewn into the armhole, and raglan sleeves, which extend in one piece from the collar to the underarm, providing a sporty look. Other popular styles include cap sleeves, which are short and cover only the shoulder, and bell sleeves, which flare out at the wrist. Each sleeve style can dramatically change the overall appearance of a piece of clothing, making it suitable for different occasions and personal preferences.
