Are flare leggings and classic leggings developed the same way?

No, flare leggings and classic leggings should not be developed with the same fit logic. Classic leggings focus more on compression, waistband stability, and full-leg recovery. Flare leggings need additional attention to drape, lower-leg shape, movement, inseam proportion, and lifestyle styling. The fabric may need a softer compression feel or more flexible movement. If the flare opening, knee area, or hip fit is not balanced, the style can lose both comfort and shape.
