Size 0 which is an X Small.

I would say best fit AU 6 - 8 (I'm an AU 10 and this fits but a little tight in the arms). 

Beautiful material.

It's so artisan! 

Designed and handmade in Melbourne by mother-daughter team.

A special piece, very well looked after by me - but no longer fits well.

Letting go for a fraction of the price, hope it will be loved and worn.
