Lululemon just co-signed the Y2K trend with a new drop of covetable retro pieces in a campaign featuring Hannah Berner. 

The brand recently appointed the The Giggly Squad star as an official Lululemon Abassador for the US Open, and her campaign is shopable now!

Think Y2K-inspired tracksuits, oversized pants, lightweight layers, and cozy matching sets that will take you everywhere both comfortably and stylishly, from the office, to the gym, to after-school pick-up.

Y2K style is still having its moment, and the retro sportswear revival feels especially right for fall. We're shopping for throwback styles that feel distinctly current. For example, retro windbreakers—a growing celeb-approved fall trend, by the way—wide-leg silhouettes, low-rise waistbands, and contrast trim details are all making sporty dressing feel cool again, while completely modern.

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, like ayered sports bras, colorblocked tracksuits, and co-ord sets that read as nostalgic and retro-cool, but ultimately evergreen, so you'll wear them for a long time—and those are always the best trends to invest in. 

In summary: These are the versatile pieces to lean on in your activewear rotation. Lululemon's performance fabrics and most-loved silhouettes, now with a Y2K refresh, and some are even in Lululemon's discounted We Made Too Much section already.
