The shift toward fashion-first colorways and sneaker-matching designs in fashion jerseys marks a big evolution from traditional sports fandom to intentional streetwear stylings. The colors for men's and women's jerseys on the field are often based on function — think contrasting, neon colors meant for cross-field visibility.
In the fashion jersey trend, colorways are chosen for aesthetic appeal and collectibility. For example, fashion kids' jerseys like this Mitchell & Ness Ken Griffey Jr 1991 replica jersey feature alternate colorways to rep your specific style.
Kicks are also an essential part of this look, coming from sneaker culture's long tradition of matching apparel colors to shoes. Jerseys produced in alternate colorways by brands like Nike and adidas are often designed to mirror their most famous streetwear styles for a totally cohesive look.
