Answer by Syama Meagher:
There is a market for everything. The high margins they make on the smaller sized goods selling at full price allows them to compensate for non selling larger sized goods. It is also skewed appropriately when buyers are looking to sell for all sizes- often times following the format of XS (1), S (2), M (2), L (1), XL (1). Certainly this depends on the product line and where the brand is distributed. In addition, brands often will consolidate goods to where it is selling most. Meaning XL’s will get consolidated across the country to better service that market.
