Hi,
Women’s trousers are infinetely more complicated than men’s. When developing women’s pants, I like to start from the silhouette, drape and mold of the pant, but not after deciding on material. Nearly all nonstretch materials are fairly easy. Secondly, I decide the position of the waist. From there I decide the shape of basin. So, really, the material is everything, especially with strech qualities. Basically, other than having a crotch, in- and outseams, the pattern of a stretch pant has virtually nothing to do with that of a non stretch trouser. Just as a small sidenote; when Ibfirst started fitting women’s jeans in the late seventies every fitting model was able to hold a sheet of paper between her knees when her feet were put together. In contrast, these days, most models have a hard time doing the same with a pingpong ball. Just to illustrate in what ways women’s bodies have changed...
Cheers, Hendrick
