What is a size curve?
How demand splits across the sizes within a style.
Why it matters: Buy the wrong curve and the popular sizes sell out early while the ends sit and get marked down.
How it's worked out: Express each size as a share of total sales for the style or a similar one (e.g. 10/25/35/20/10 across XS–XL).
