Size Change FAQ's
What has changed with sizing?
We’ve updated the Alpha size labels (XS, S, M, L, XL, XXL) to better align with global sizing standards.
We’re shifting our Alpha size labels up by one to match the international market. For example, what was previously labelled an Extra Small (which was a numerical AU 8) will now be labelled a Small. Rest assured, your numerical size hasn’t changed - an AU 8 is still an AU 8.
This update simply means:
An AU 6 was an XXS but is now aligned to XS
An AU 8 was an XS but is now aligned to S
An AU 10 was a S but is now aligned to M
An AU 12 was a M but is now aligned to L
An AU 14 was a L but is now aligned to XL
An AU16 was an XL but is now aligned to XXL
The easiest way to shop is to always choose your numerical size. This is the sizing we are prioritising across the site.
Why have you introduced new sizing?
As our global community grows, it's important that our sizing reflects international norms. This change helps us stay consistent with the way sizes are labelled across the world, making it easier for you to find your perfect fit, no matter where you are.
How do I know what products have new sizing?
Styles using the new system will be clearly tagged with a special sizing flag, so you’ll always know when it applies.
When shopping collections & products, you'll now see a NEW SIZING Flag on the top right hand corner of the image, as seen below:
When shopping products you'll now see 'NEW' next to Size Guide, as seen below:
What's the easiest way to choose my size?
Just choose your usual numerical size (e.g. AU 6, 8, 10, 12, 14, 16) - that hasn’t changed. The shift only affects the Alpha label (e.g. from XS to S), so your fit remains the same.
Do all products use the new sizing
Not yet. We’re gradually transitioning. Look for the size flag on each product to see if it has new sizing. All future collections launching from 23rd December 2025 will use the updated Alpha sizing.
