The article discusses a small but often overlooked detail on sweaters and hoodies: a triangular piece located just below the neckline. While many people view this triangle as simply a decorative feature, its inclusion is rooted in the practical needs associated with the original designs of these garments. The triangle was utilized when sweaters were not a fashion staple but were rather designed for demanding physical activities.

As time progressed, the purpose of the triangle faded alongside the evolution of the sweater into a more urban and everyday wear item. Despite this shift in function, the characteristic triangle remained a persistent element in the design of these garments. This persistence illustrates how elements of clothing can carry historical significance and remain as remnants of their original purpose, even in contemporary fashion.

Ultimately, this insight highlights the intersection of design, function, and fashion, reminding us that even small details in our clothing can have stories and meanings that reflect larger shifts in cultural and practical needs over time.
