Length and width ought not be yoked like that, an XL shouldn't be longer, just wider. You need Short, Medium, and Tall and Extra Tall for that dimension.

I was a tall and skinny kid and the heartbreak of never having pants long enough, because the small ones were all also very short, still I feel it!

As an adult, the first time I saw a ladies size Small Tall in the shop I almost cried.

Women's bra sizes also suck, because the volume of the cups is tied to the diameter of the half circle the underwire describes, but small boobs aren't small in width, they just sit closer. Champagne glass, but small bras assume shot glass instead, basically. They need three measurements.
