As a woman, I often feel frustrated by typical off-the-shelf clothing sizes, and I'm sure you do, too. The standard numerical sizes 2, 8, 14, etc. reveal almost nothing about how the garment will actually fit me as a labeled size 10 woman. And don’t get me started on Small, Medium, XL. How many of us have every single one of those sizes in our closet? Size inconsistency has existed since at least 1937.
