Seed Heritage Size Chart
Australian fashion · women's
Seed Heritage is an Australian brand using AU numeric sizing from 4 to 18, with a letter mapping where a 10 is Small, 12 is Medium and 14 is Large, and a centimetre-native chart. A size 10 fits a 90–95cm bust, 70–75cm waist and 97–102cm hip. Seed sizes to a fairly slim, tailored silhouette, so its pieces tend to fit close through the waist and shoulders — shoppers who carry weight there, or who prefer a relaxed fit, often size up one. Unlike most Australian brands, Seed publishes a full international conversion (AU 10 = UK 8 = US 6 = EU 38), which makes it easy to cross-reference against imported labels. Seed is a frequent secondhand find and its tailored pieces hold their shape, so the size tag is reliable for structured items; check the listing photos for any relaxed knitwear, which wears looser than the chart implies.
Seed Heritage uses AU numeric sizing (4–18) with an XXS–XL letter mapping, and publishes an official AU/UK/US/EU conversion. Its chart is centimetre-native.
