What does the 'woven and knit mix' in the product description mean?

Woven holds its shape straight, and knit stretches softly. Woven, a fabric woven by interlacing yarns horizontally and vertically, creates a firm outline without losing shape, while knit, a knitted fabric made by looping yarns together, has elasticity and moves flexibly. They are two materials with different weaves and characteristics.

threetimes's Layered knit top was designed by weaving these two contrasting fabrics together into a single garment^[1]. The neckline also overlaps two different shapes. An open collar style with folded-back lapels is placed together with a round neckline that encircles the neck^[2]. hmmm, just as the round neckline and collar overlap, the two different fabrics create layers as if naturally worn layered in a single garment.
