Thanks for the feedback Natasha.
Generally, our sizing runs more generous than typical Australian sizing.
As a rough guide, our sizing runs as follows; XS is an 8-10, S 10-12, M 14-16, L 16-18 and XL 20-22, but we always include comprehensive descriptions for each product with fit details, and fabric makeup. There is also a size guide under the item description for each product and we're always happy to help via email, phone or DM if you have any questions too :)
We hope this helps for next time!
