Good fabric, treated gently, outlives trends by years. Two minutes of reading per fabric - then forget about it.
[Instructions below are placeholders until Jack confirms against the actual fabric content labels].
More than any single instruction.
Cold water, always. Heat is what ages fabric - not washing itself.
Zip and button before washing. Open hardware is what chews other pieces.
Skip the dryer when you can. Line-dried pieces keep their shape and color measurably longer.
Wash less. A dress worn two hours to dinner needs air, not a cycle.
Stains get one gentle try first. Blot, cold water, patience - before anything stronger.
