Fishnet tights have a open net weave which stretch out when worn. They are a popular choice for Tap, Jazz and Cabaret Dance styles, and often used to create funky looks for costuming.
For a traditional and uniform look, fishnets are often worn over shimmer (gloss), or matte tights. This is particularly good for uniformity in troupes.
Professional fishnets are recommended for continual use due to their durability.
