Most KNOTS FOR DARLING pieces are designed for a relaxed, effortless fit. 
Our clothing is currently made in the following sizes (Australia sizing):
XS/S: 6, 8 
S/M: 8, 10, 12 
M/L: 12, 14 
O/S - one size... suits 6 - 16 
We recommend checking your measurements and then see where they fit in the below chart to help you choose a size. The size range allows for an oversized look up to a fitted look. 
(Please refer to the following as a guide only)
  *For instance, if you have Bust 86cm / Waist 70cm / Hips 95cm - an XS/S will fit fine, however it will be fitted, especially at the hips. The S/M will be perfect and the M/L would be quite oversized.
We personally love an oversized look that allows for lots of styling of the dresses with knots, belts and tucks.
