Loose
Designed for everyday wear, this cut balances relaxed legs with a flattering waist, making comfort and style go hand in hand.
Styles: Joan • Elisabeth • Noah • Alice
Barrel
Inspired by the ‘80s but designed for today, this cut is all about style and comfort. Roomy through the leg, snug at the waist, and tapered at the ankle.
Styles: Leila • Kimmy • Leyda
Straight
Straight cut from the hip to the ankle. Because of their simplicity, they've been a staple for decades and are the ultimate “go-to” classic denim style.
Styles: Liora • Emiko • Inoe
SHOP STRAIGHT FIT
Flared
Our Flared Jeans take the amazing vintage energy of the '70s and give it a clean, modern touch. They fit snug at the waist and hip, offer a comfy feel through the thigh, and gently open into that signature flare below the knee.
Styles: Kukiko • Jane • Tiy • Tanja
Skinny
Intentionally designed to fit like a second skin. We gave them that flattering, very tight fit, but added the right amount of stretch for total, all-day comfort. They move with you without losing their shape.
Styles: Juno • Emi
SHOP SKINNY FIT
Tapered
Tapered fit jeans are high-waisted and offer a little bit more room around the waist and hip area. Form-fitting, but not too tight.
Styles: Caroline

STRETCH DENIM
RIGID DENIM
STRETCH DENIM_
Our Stretch Denim blends premium cotton with just the right amount of stretch for ease of movement without losing shape, perfect for those who want flexibility without compromising on an authentic denim look.
How to choose the right size? Stretch denim bounces back to its original shape, preventing sagging. Over time it may lose elasticity, especially if not washed properly.
KOI stretch levels:
- Low Stretch (1–2% elastane) – Feels more like traditional denim with slight flexibility.
- Medium Stretch (2–5% elastane) – Offers a balance of comfort and support.
RIGID DENIM_
How to choose the right size? It depends on your desired fit. Do you like a tight fit? → buy true to size. It may feel snug at first, but rigid denim stretches ~0.5-1 inch (~1-2.5cm) with wear. Do you prefer a more relaxed feel? Size up 1 size.
Waist & thigh fit:
- The waistband should be snug but not painful — it will stretch over time.
- If you have bigger thighs, consider a relaxed or tapered fit instead of sizing up too much in the waist.
