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.
