Each word of the jean's name is a description of the fit and length. ie: "Bumster" refers to the standard low rise, "Vegas" means that the jean will finish in a skinny fit AT the ankle.
Here is a table of Riders by Lee fits:
- Mid-Straight: sit just below the belly button. Contoured and slim from hip-to-knee and continuing straight down to the hem. - Mid Vegas: medium rise, skinny jeans with a skinny fit which finishes at the ankle. All jeans that have Vegas in the name finish at the ankle. - Bumster Vegas: Standard low rise. Not as low as a Low rider but not as high as a Mid rise, the perfect in between. The leg is slim-skinny finishing at the ankle as a Vegas jean does. - Bumster Skinny/SuperSkinny: Bumster rise skinny leg - Hi Rider: High waist which sits above the belly button with a cropped leg length and flattering back pockets
Because Levi's offers a wide range of in-leg and waist sizes the sizes below were taken off a 28" waist size. As the waist and in-leg lengths vary the measurements will vary accordingly.
