Lululemon’s Y2K-Inspired Athleisure Is Here for Fall

Your fall uniform just got a Y2K update. Lululemon’s newest arrivals feel like a modern blast from the past, right in step with fashion’s obsession with all things early aughts. This collection is happily nostalgic, but updated with modern silhouettes and rich autumnal shades that make these pieces perfectly on-trend for fall 2026.

The tracksuit trend picked up last fall, when Saint Laurent sent vintage-looking windbreakers down its Spring 2026 runway, with stars like Hailey Bieber, Charli XCX, Rosé, Olivia Rodrigo, and more quickly adopting the retro windbreaker trend.  

Now, lululemon is bringing that same throwback energy into your activewear for the transitional season. Think vintage-inspired track jackets with matching joggers, colorblocked sets, and cozy layers that’ll simplify the tricky summer-to-fall stretch. 

The drop includes plenty of bestsellers, like the viral Define jackets, celeb-loved Align leggings, and more, now with a stylish Y2K touch, like contrast trim and layered details. 

Try the throwback trend with pieces that will remain timeless. Layered sports bras and colorblocked tracksuits read as retro cool, but ultimately evergreen, so you’ll wear them for a long time—and those are always the best trends to invest in.
