From Seamwork:
The Elaine pants are a staple wardrobe piece with polished details. Version 1 fits like traditional trousers, featuring three front darts, slant pockets, side zipper, a notch at the back waist, and welt pockets with button tabs.
Version 2 has a bold silhouette with a culotte shape. The pant legs are constructed from two panels with a seam slit from the top of the knee to the hem. The pants hit at the waist, have slant pockets, close with a side zipper, and the back features a notch at the center waist.
