Materials & Care

  • Composition: 100% organic cotton (pointelle knit).

  • Dye method: plant-dyed base; mild tone differences are characteristic.

  • Care: turn inside out; wash cold on gentle with similar colors; no bleach or optical brighteners. Line dry or tumble low. Cool iron if needed (avoid trims).

  • Note: a light surface tint may release on the first 1–2 washes-wash separately at the start.

Quick links: Safety Guide | Certificates & Lab Reports | Why Plant-Dyed

  • Will color fade? Plant-dyed shades mellow gradually; cold wash and low heat help retain tone.

  • Color transfer? A little surface pigment may release early-wash with similar shades.

  • Is pointelle see-through? It’s an openwork knit; pair with a diaper cover for bright photos.

Fit & Sizing

  • Regular fit. Manual measurement tolerance: ±1–2 cm.

  • Tip: between sizes? Choose the next size up for longer wear.

Pointelle is an openwork knit that promotes airflow while staying gentle on skin.
