Why is the sleeve line of the denim trucker jacket designed in a curved shape?
This question is asked out of curiosity about how the silhouette and arm movement are realized when wearing a jacket made of stiff denim material.
RECTO's signature denim trucker jacket holds a firm shape in the body while curving the sleeves into a three-dimensional form, creating natural arm movement and a balanced contour.
The body holds its shape, and the sleeves curve around[1].
Generally, when thick and densely woven fabrics like denim are sewn in a straight line with flat-felled seams, the joint areas tend to meet stiff resistance when moving the arms. To relieve this, when patterns are cut into curves tailored to the natural bending angle of the arm, the fit feels noticeably softer even with firm denim.
RECTO placed the sleeves into a curved shape based on the structural form of the body[2]. From the front, the jacket's distinct neat contour stands out, and from the side, a gentle three-dimensional feel comes alive along the arm.
hmmm, it is a thoughtful construction that provides mobility through a curved pattern without breaking down the silhouette of substantial denim.

How many cut panels were combined in the sleeves to realize the curved sleeves has not yet been confirmed in official materials.
