fishnet

Fishnet refers to a fabric or textile that features an open, diamond- or square-shaped mesh created by interlacing threads. It has two broad uses: as fishing nets and as decorative or functional fabric in clothing and accessories.

In fishing, fishnets are nets designed to capture fish, made from synthetic or natural fibers such as nylon, polypropylene, or cotton. Netting varieties include gillnets, trammel nets, seines, and purse nets, with mesh size chosen to target certain species and minimize bycatch. Regulations in many regions govern mesh sizes, materials, and net designs to protect juvenile fish and protected species and to reduce environmental impact. Ghost nets—abandoned or lost nets—pose ongoing ecological concerns, continuing to drift and trap wildlife.

In fashion and textiles, fishnet describes a fabric with a regular open mesh, typically in a diamond pattern, used in hosiery such as tights and stockings, as well as dresses, skirts, and accessories. Fabrics are commonly made from nylon, polyester, or blends that include elastane for stretch, and they come in varying mesh sizes from fine to very large. Fishnet textures are employed for aesthetic effects, performance costumes, or streetwear, and can be plain or patterned and dyed in different colors. Care usually involves gentle washing and avoiding snag-prone environments to preserve the open structure.

Historically, netting originated as a practical tool for fishing, while decorative open-mesh fabrics gained popularity in the 20th century and have since seen varying cycles of fashion interest.
