Jeggings were brought on by the resurgence in style of skinny jeans in the mid- to late-2000s, when a higher demand for an even tighter style of pant came about. Since jeggings are typically made of a denim/spandex blend, they are often worn on their own as opposed to under a skirt or dress. Some jeggings have front fastening facilities while others just have an elastic waistband and no pockets.
With respect to material, jeggings fall into two main categories:
- Jeggings that are legging material made to look like denim with fake pockets and belt loops
- Jeggings that are a true cross between denim and legging material. "Denim jeggings" are essentially a denim fabric with the elasticity of a legging.
The latter are more similar to skinny jeans than the former. Some designers call "denim jeggings" pull-on jeans rather than jeggings.
Fashion trend 
Jeggings entered the fitness world in early 2009. Jeggings were among the more popular clothing items of 2010, according to business reporting.
Popular culture 
In 2011 "Jeggings" was entered into the twelfth edition of Concise Oxford English Dictionary. Conan O'Brien wore a pair during the taping of Conan on 2 December 2010, the night after admitting his (tongue-in-cheek) love for jeggings to Project Runway's Tim Gunn.
