The problem is best understood from a supply chain management perspective. A clothing retailer ordered that stuff six months ago and they only took a two minute glance (if that) at the one model sized 'medium' garment the wholesaler got the supplier to make. Every other size was just a tickbox with some guesses made as to how many items to stock to get through the sales season. The importer took the orders from retail and topped up the order so they can do some mid-season re-stocking. They know that they have to get the order right as it is not as if the product is going to be made again. The retailer does not have to make a sale from every customer that walks through the door. For people with XXS or XXL size requirements they might only have something to sell, the one coat in the super-sized option. Even this may be a carryover item from a previous season, kept in stock for the guy with arms that reach down to his ankles. It is quite a risk to get the sizing wrong, you can't have a garment on the shelves with just the XXS and XXL sizes with nothing in-between. If this happens then it is straight to the sale rail. Particularly if the supplier didn't overstock the popular sizes. We also live in an age of fast fashion where people buy clothes the whole time. Truth be told, if everyone out of childhood stopped buying clothes today we wouldn't have a mass nakedness problem for years. Clothes are that abundant. There have always been tailors and dress makers that will make clothes to fit any body, maybe a service for this is needed rather than a newsletter about what trousers in the world of fast fashion can be squeezed into.
