Those who are members of the militia are currently defined in Title 10, section 311. All men from 17 to 45, and with prior service to age 65, and women who are members of the National Guard.
A better consitutional definition would be in the Militia act of 1792. That is even broader.
But it is important to note that the founding fathers distinguished between the Militia and the People.
Still, I would like it if the definition of Militia was expanded to include, as a minimum, all married women 17 to 65, or mothers of a minor child. If they are not suitable for deployment to further public safety (offensive or defensive operations, or rescue work, they can at least defend themselves and their families so their husbands/sons can be available for deployment.
"The weather being changeable, the right of the people to own clothing shall not be infringed" would not allow the government to confiscate or forbid clothing if the weather does not then vary nor does it require that people possess or wear clothing.
