If married lady, do you address them as madam? Or Mrs. Or Ms.

When a MILF still a Ms.

depends on how old and age difference.
usually only reserved for those 20 years apart or officers in uniform.

mrs only if confirm married and a non acquaintance.
miss for all situations except when she looks very old,

just call her by name if she's my acquaintance
