Another company we’ve ordered from is called Minus33. Now, I have only ordered men’s long underwear bottoms from them. They are more of a mid-weight long underwear, they are soft, seem comfortable and perfect for what my son will need this winter. They do have a smaller selection compared to some of the other companies, but they do carry long underwear for kids (although it looks like it’s just one pink for girls and black for boys). Their prices seem reasonable compared to the other companies and they do sell some of their products on Amazon.
