Idea

It´s really not okay and kind of funny- especially for the reason that amazon merch is only available in the USA, yet! Fast Food, Ice Cream, Burgers--- and XL! Haha...

I agree that it isn't totally ideal...but...there are certain reasons why under the current Merch setup they only offer the sizes they do: 1) Availability: For the "Anvil" (i.e. standard) Merch shirts the Ladies ones are only actually available up to a largest size of 2XL. The same applies to the "Bella+Canvas" (i.e. premium) Merch shirts which are again only available up to 2XL in the Ladies fit 2) Cost: Currently the Merch platform works on a "one price fits all" system where ALL sizes and ALL styles in a single listing cost exactly the same amount. But not all sizes/styles of shirt cost the same. For instance if you take the "Anvil" shirts as an example then the Small through to XL Men's shirt stock would cost roughly $2.30 but 3XL Men's shirt stock would cost roughly $5.55, and for women Small through to XL Ladies shirt stock sizes would cost roughly $3.00 but a 2XL Ladies would cost roughly $5.25 which is 75% more expensive. Perhaps if the Merch platform ever changes to a "price by cost" system then they can add in other sizes and brands/styles. 3) Fit: The "Anvil" Ladies shirt style is intended as a "semi-fitted and contoured" shirt, and I'd imagine it's less likely that larger ladies needing a 3XL or higher would be wanting a shirt that's intended to be slim-fitting or figure-hugging, so they could just buy the Men's (which is actually a "Unisex" but sold as men's on Amazon for sales/click-thru reasons)
