How to measure at home
Use a soft tape measure and take each measurement against bare skin or a thin layer. Stand naturally — don't suck in or stretch up. If you're between two sizes, the larger one usually gives a more comfortable everyday fit.
Frequently asked
I'm between two sizes — should I size up or down? For our compressive leggings and shorts (Celestial, Lavish), most women prefer their smaller size for the snatched, supportive feel. For our halters, jackets and crops, the larger of the two sizes will give a more relaxed, comfortable fit. The "details" section on each product page has style-specific guidance.
Does this guide apply to every LUSS piece? It's a general guide based on body measurements. Because each silhouette is cut differently, always check the "details" section on the product page for the most accurate fit advice for that specific style.
What is the largest size LUSS offers? Our standard range runs from XS (AU 6–8) through to 4XL (AU 20–22). Size inclusivity is a brand pillar for us, and the majority of our pieces are offered across the full range.
I'm shopping from outside Australia — what size am I? Use the international conversion table above. For example, a US 8 is a LUSS L, a UK 12 is a LUSS L, and a EU 40 is a LUSS L.

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.
