Meet ChiChi:
She’s the high-waisted brief that hugs you tight, smooths you out, and lifts you up — all without breaking a sweat.

Her thick, sculpting waistband is built to have your back (and your belly) on the days you need to feel supported, secure, and maybe a little extra snatched.

Made with our signature blend of smooth and textured Lenzing TENCEL™, ChiChi is breathable, soft, and confident as hell. She gives you that held-together feeling without holding you back.

Heads up: ChiChi’s waistband means business.
She’s firm by design — so if you want a softer fit, size up. And if firm undies aren’t your thing, you might want to try another NAT'V style. No hard feelings.

Your NAT’V pieces are made with luxe, sustainable fabrics — from Organic Cotton to Lenzing Modal and Recycled Nylon. To keep them soft, supportive, and planet-friendly for longer, show them a little care:

1. 
   Wash gently — Cold or warm machine wash (up to 40°C) on a delicate cycle with similar colours. This cleans effectively and protects your fabrics.
   
2. 
   Keep it hygienic — Everyday washes at 30–40°C with good detergent are enough to kill bacteria. If you want extra freshness (like after being unwell), you can do an occasional hotter wash — just don’t make it a habit, as high heat breaks down elastic and fibres.
   
3. 
   Use kinder detergent — Mild, eco-friendly detergent only. No bleach, no softeners, no harsh chemicals.
   
4. 
   Skip the dryer — Line dry in the shade. Heat from dryers or direct sun weakens elastic and damages fabrics.
   
5. 
   No ironing needed — Our fabrics are designed to stay smooth and comfy without it.

✨ Treat your NAT’Vs with love, and they’ll love you longer.

All yarns used in Natv meet the OKEO Tex Standard 100. We source from a variety of materials, including certified Lenzing Modal, organic cotton, and recycled materials. Our signature range has undergone SGS testing for forever chemicals and is certified free from them.
