A type of edge finish on fabric, especially on the inside of clothes, that prevents fraying.
Sergings are important for making clothes last longer and look neat.
Examples:
She used sergings to finish the edges of the dress.
The sergings on his pants were coming loose.
I like the way the sergings make the inside of the shirt look neat.
The sergings on her skirt were so fancy, they looked like lace.
The sergings on his jacket were so strong, they never came undone.
I learned how to do sergings on fabric in my sewing class.
