What kind of shape does the 'blouson detail' mentioned in the cardigan description refer to?

This appearance is reflected in the actual measurement of a 31cm hem width^[1]. A blouson refers to a garment shape where the waist or sleeve ends are narrowed, gathering the upper volume into a rounded shape. This cardigan from Low Tide is made with a total length of 52cm, chest width of 44cm, and hem width of 31cm^[2]. Rather than falling straight down, the hem gathers narrower, neatly settling the extra fullness of the upper body so that it rests slightly above the waistline^[3].

The sleeve cuffs are finished in the same manner. This detail is applied not only to the hem but also to the sleeve openings, narrowing the circumference toward the wrists so the sleeve volume gathers^[4]. The outer surface of the garment is knitted with 100% nylon yarn featuring long hair, and this three-dimensional, tapered shape combined with the texture of the long hair creates an overall rounded curve^[5][6].
