Thanks for that explanation.
We don't have any sort of federal or state programmes here for low income families for school uniforms or food.
In my state a (and, I suspect, every state), if a family is unable to buy their own uniform then the school principal has the discretion to provide them out of school funds, or refer the family to the relevant welfare agency. As a former PTA president I oversaw running of the uniform shop and tuckshop. I don't recall any cases (in my time) of the school buying uniforms to hand onto families, so either no one approached the school about it, or they got free/reduced uniforms via other means. We also sold second hand uniforms at very reasonable prices, which families of all income levels availed themselves of.
Slight threadjack: Few, if any, schools provide a sit down, canteen style lunch here. It's either bring your own, or order from the tuckshop (usually before school for pick up later). Individual schools have been known to provide (free) breakfast programmes for some students, but they're few and far between and a decision made entirely at school level.
