Jeggings Vs Leggings

If you're wondering what is "Jeggigs" well very simple, their "leggings" and "jeans" combined. Its the latest fashion term. Now you must say that they look like skinny jeans ! WRONG ! The Fabric of the "Jeggigs is much softer and waists are elastic, no pockets, no zippers !

Where to find them ?

Dorothy Perkins - They have 3 colors (Black, Grey, Navy blue)
Top Shop - 3 colors (Black, Grey, Navy blue)

Ps: Im just wondering will the fashion industry  be calling "reggings" for red leggings and so on ?? Do you think this Terminology is a bit to much ?
