The 2026 denim guide: trending jeans, colors, and brands you need

Denim is the hardest-working category in our wardrobes, but the trend cycle for jeans has shifted drastically over the last few years. If you are still holding onto your skin-tight jeans from 2016, it might be time for a structural update.

Spring 2026 is all about comfort, vintage washes, and relaxed silhouettes. The best part? Because heavy, rigid denim requires a serious break-in period, buying your jeans second-hand means someone else has already done the hard work for you. Here is your guide to the biggest denim trends of the year and how to thrift them on Sellpy.

1. The baggy / relaxed fit

The skinny jean is officially resting in peace. The defining silhouette of 2026 is loose, baggy, and relaxed from the thigh to the floor.

Brands to search for: For the perfect puddle-hem baggy jeans, filter for Weekday (specifically their Astro or Rowe models), Acne Studios, or the iconic vintage Levi's SilverTab collection.

2. Dark wash & raw denim

While light-wash denim is a classic spring staple, deeply saturated, dark indigo, and raw denim are having a massive moment. They look incredibly polished and instantly elevate a simple t-shirt.

• The thrift hack: Look for unwashed or "raw" denim from brands like Nudie Jeans or A.P.C. Finding these second-hand is a massive win because the stiff fabric has usually softened up beautifully.

3. The low-slung Y2K silhouette

For the fashion-forward, the waistline is dropping. Low-rise and mid-rise jeans that sit relaxed on the hips are fully back in rotation.

• What to look for: To get this authentic Y2K look, you need authentic Y2K brands. Search for vintage Diesel, Miss Sixty, or early 2000s Guess denim.

4. The holy grail: vintage levi's 501s

Trends come and go, but the vintage Levi's 501 is eternal. A perfectly faded, straight-leg 501 is the ultimate denim investment.

• The thrift hack: Vintage Levi's sizing is notoriously tricky because 100% cotton shrinks over time. Always check the actual measurements in the Sellpy listing, and don't be afraid to size up by one or two sizes from your modern stretch-denim size!

5. Ecru and butter yellow denim

If you want to step away from traditional blue jeans, Spring 2026 is bringing a wave of soft, colored denim.

• What to look for: Swap stark white jeans for a softer "ecru" (unbleached natural cotton) or the trending "butter yellow." They pair perfectly with lightweight spring knits and loafers.
