Sammy’s Window is a “thrift shop” for foster kids.

Isabel’s House might be interested, they are a crisis nursery - basically, if kids need an emergency place to stay (Mom is getting away from an abusive partner and needs a few days to secure housing, for example), they take them in and care for them until arrangements can be made.

Harmony House is a domestic violence shelter and usually women and kids arrive with not much more than the clothes on their backs - they would probably appreciate them too.
