This calculator assesses a fabric's ability to return to its original shape after being stretched. You'll input the fabric's fiber content (e.g., percentage of spandex/elastane) and its weight. The calculator then provides a 'Stretch Recovery Score,' indicating how well the fabric will hold its shape over time. A higher score means better recovery and less sagging or bagging.

Good stretch recovery is essential for a great fit, especially in lingerie that needs to hug the body's curves. Fabrics with poor recovery will stretch out and lose their supportive qualities quickly, leading to a sloppy fit. This calculator helps you understand the quality of the fabric before you buy, ensuring you choose pieces that will maintain their shape and support wear after wear.

The Stretch Recovery Score is a numerical rating of the fabric's resilience. A high score (e.g., 90%+) is excellent, indicating a durable fabric that will snap back into shape. A low score might be acceptable for loose-fitting sleepwear, but for a supportive bra or form-fitting panties, you'll want a higher score. Use this to assess the quality of garments and predict how well they will last.

• When shopping, look for a spandex or elastane content of at least 5% for items that need to hold their shape.
• Gently stretch a corner of the fabric in the store. If it snaps back quickly, it has good recovery.
• Avoid over-stretching your lingerie when putting it on or taking it off.
• Giving your bras a 'rest day' between wears allows the elastic fibers time to recover.
• Even fabrics with great recovery won't last forever. Know when it's time to replace a worn-out piece.
