Tracksuits are worn not only as athletic wear, but also as relaxing clothes to lounge in. The designs are almost always functional, but occasionally use colors and motifs that some could consider stylish.
Natsuki Subaru (from Re:Zero − Starting Life in Another World) or Kageyama and Hinata (from Haikyu!!) are known to be wearing a tracksuit as their trademark. Which character below do you think is rocking the best outfit?
