The world-famous raglan sleeve is closely linked to the events of the Battle of Waterloo and the Crimean War in Russia. It is named after FitzRoy James Henry Somerset, better known as Lord Raglan. This field marshal and commander of the English troops became famous not only for his military achievements but also left a mark in the history of fashion.

In 1815, during the Battle of Waterloo, Lord Raglan sustained a serious injury and lost his right arm. Due to the slowly healing wound, wearing clothing with a regular armhole caused pain from the rubbing seams. The field marshal then turned to a local tailor, who suggested a new sleeve cut that started right from the neckline. The sleeve was cut together with the front and back, forming a single piece, and the shoulder seam was absent. This clothing model was the most comfortable for Lord Raglan after his amputation.

During the Crimean War from 1853 to 1856, the raglan was widely used in the clothing of English soldiers. The weather in Crimea was capricious and rainy, so the raglan gained popularity among the soldiers. The absence of a seam prevented water from penetrating under the clothing, ensuring comfort.

Lord Raglan's life ended in Russia; he died of cholera near Sevastopol in 1855. The raglan sleeve, developed by an unknown Russian craftsman and named after the English field marshal, gained worldwide recognition and remains one of the most practical and comfortable designs. Since then, the technology for its tailoring has hardly changed. Today, raglan is used in both military uniforms and everyday clothing, including t-shirts, sweaters, hoodies, and dresses.
