raglan sleeve

A Raglan sleeve is a type of sleeve design where the sleeve extends in one piece fully to the collar, creating a diagonal seam from the underarm to the neckline. Unlike traditional set-in sleeves, Raglan sleeves have no shoulder seam, resulting in a sloped, sporty appearance. This construction allows for more freedom of movement and ease of wear, making it popular in casual and athletic clothing like baseball shirts and sweatshirts. The distinctive diagonal seam is both functional and stylistic, providing a seamless armhole and a streamlined fit.
