Spandex (elastane/Lycra) is the stretch fibre behind a comfortable, flexible fit — blended into most lingerie.
Lingerie fabric
The essentials
- A synthetic fibre with exceptional stretch and recovery.
- Feels smooth and hugging — it moves with you.
- Hand-wash or gentle cycle; keep it away from high heat.
- Blended in for fit and shape retention.

Good to know — porosity, safety & the honest detail
Is spandex breathable?
On its own, moderately — spandex is usually blended in small amounts (5–20%) with breathable fibres like cotton or nylon, so a garment’s breathability depends on the blend. A cotton-rich blend breathes noticeably better than a fully synthetic one.
Does spandex stretch out over time?
It can lose some recovery with heat and age. Hand-wash or use a gentle cycle, skip the dryer and hot water, and it holds its stretch far longer.
Is spandex the same as elastane and Lycra?
Yes — elastane is the generic name, spandex is the common US term, and Lycra is a well-known brand. All three are the same stretchy fibre.
Spandex vs Nylon
| Spandex | Nylon | |
|---|---|---|
| Role | Stretch & recovery | Strength & smoothness |
| Stretch | Exceptional | Low |
| Feel | Hugging | Silky |
| Common use | Blended for fit | Hosiery, shells |
How to care for Spandex
- Hand-wash cool or use a gentle cycle.
- No bleach; avoid high heat and the tumble dryer (heat kills the stretch).
- Reshape and lay flat to dry.
