FAQs – Everything You Need to Know

Is the ChiChi Brief good for everyday wear?
Yes! It’s designed for daily comfort with shaping support that feels soft and breathable.

Will it show under fitted clothes?
The semi-seamless cut and smooth eco fabric make it nearly invisible, even under slim fits.

Should I size up?
If you’re between sizes or prefer a softer fit, we recommend sizing up. The waistband is designed to sculpt without restricting.

Is it sustainable and safe?
Absolutely. It’s made from eco-certified Lenzing™ Modal and tested to meet global OEKO-TEX® standards.

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.
