The fabric we chose, CoreForm™
When we restarted LUSS, we knew the fabric had to come first. Before the cuts, before the colours, before everything else. Because no design works if the material doesn't.
After months of testing across mills, weights and finishes, we chose CoreForm™ and built the FORME collection around it.
What CoreForm is
CoreForm is a premium Nylon + Lycra Sport blend, woven to 220gsm. It's the kind of fabric you'll find in considered, longer-loved activewear, soft against the skin, structured under tension, and quietly recoverable wash after wash.
Composition: Nylon + Lycra Sport Weight: 220gsm Finish: Sculpting, soft-touch, four-way stretch
Why we chose it
There's a moment in activewear that decides whether you'll keep wearing the piece, or fold it away. It's the second -wear test, when the fabric either holds its shape, or doesn't. CoreForm passed every test we put it through.
Three things mattered to us most:
Holds its shape. Even after repeated wash and wear. Waistbands stay put. Hems don't curl.
Moves with the body. Compressive without restricting. Four-way stretch so the cut sits where it should.. squat, bend, walk, stretch.
Feels considered against the skin. Soft-touch finish, no scratchy seams. Wearable from studio to slow morning without thinking about it.
Where you'll find it
CoreForm is the foundation of our FORME collection, both the Muse Halter and the Elara Flares are cut from it.
Our All Day Every Day fabric (used in the Celestial range) and Signature fabric (used in the Lavish range) are part of the same considered family — slightly different weights and finishes, chosen for the same reasons.
A note on transparency
We didn't design CoreForm. We chose it.. carefully, after testing dozens of alternatives. That distinction matters to us. The right fabric is the foundation of a piece made to be worn for years, and we believe in being honest about where that foundation comes from.

HOW TO CARE FOR COREFORM™
Considered fabric lasts longer when it's looked after. A few small habits will keep your CoreForm pieces feeling new:
Cold machine wash on a gentle cycle, inside out
Wash with similar tones and similar fabrics
No fabric softener, it coats the fibres and reduces stretch recovery
Line dry in the shade, avoid the dryer where you can
Don't iron, don't bleach
Is CoreForm squat-proof?
Yes. The 220gsm weight and Nylon + Lycra blend hold opacity through every position.
Will it pill over time?
Not with normal wear. CoreForm is woven to resist pilling, and washing inside out extends that life further.
Is it stretchy in all directions?
Yes — CoreForm is a four-way stretch fabric, which is why our pieces move with the body rather than fight it.
Is CoreForm sweat-wicking?
Yes. The blend pulls moisture away from the skin and dries quickly between sessions.
Where is CoreForm sourced from?
We work with a trusted premium fabric supplier we've tested extensively. For specific supply chain questions, write to us at hello@lussactive.com.
