Bachelor button (sewing)
A bachelor button is a button that can be attached without sewing. It uses a stud pressed through fabric and into a top button.[1][2] They were sold in notion stores in the late 1800s and early 1900s as an emergency repair button. They could be attached and removed.[3] The poem “A Bachelor's Button” is a lament by a man whose lover never sewed his button on his coat and had to use a bachelor's button to repair it.[4]
