This Is The Hair Length To Wear In 2025, According To The Street Style Set

The start of a new school year often sparks the urge for reinvention — and nothing says transformation quite like a new hairstyle. This season, it’s all about length.

Fashion Week may set the agenda for what’s next, but the true test of a trend is found beyond the runway. On the pavements of New York, London, Milan and Paris, models, editors and influencers become the real moodboard — and this September, their hair made the headlines as much as their wardrobes.

The street style set pushed hair length to extremes, indicating that ultra-long hair is well and truly back. Think cascading, waist-skimming strands — worn poker-straight for a sleek finish, in soft waves for an effortless ’70s vibe, or in old Hollywood curls. Whether polished or undone, the look is all about drama, fluidity and unapologetic glamour.
