We use standard Australian sizing for all of our products. Haha- we all know how unregulated sizing in the clothing industry is! Each product on our website has its own sizing information. On each page you will find the numeric or alpha sizing, plus measurements in cm. For womens clothing, we have included numeric and alpha sizing. This is because our garments carry alpha sizing tags (S, M, L, etc) and the tags can get a bit confusing because from size 18 upwards the tagging changes to unisex sizes. Don't worry, we've translated them all to the numbered sizing you are used to (12, 14, 16, etc).
If you are unsure of your size, please lay an existing tee, sweatshirt etc flat and measure width from left to right under the arms, and length from the shoulder to the hemline. Compare this with our sizing chart on the listing and go from there.
