Laundry Care
A little care goes a long way. Follow these tips to keep your Vivre pieces looking and feeling their best.
Washing
Use powder detergent. Avoid bleach and fabric softeners — they break down performance fabrics.Place each item in a laundry net on its own. Turn inside out to protect colours and prevent pilling.Wash lights and darks separately.Cold water, full cycle. Hand-washing is not recommended — too inconsistent.New item? Give it a cold wash first to rinse out any residual dye.Do not soak. Wash immediately — don't leave it sitting in water or detergent.Drying
Air-dry where possible. Best for synthetic fabrics and helps pieces hold their shape.Tumble dry on low heat if needed. High heat will reduce stretch over time.Why cold water
Cold water locks in colour, protects the fibres, and keeps your leggings and tops holding their shape. Hot water is a no for all Vivre pieces.
