The classical Greek noun that best translates to the English-language words "beauty" or "beautiful" was κάλλος, kallos, and the adjective was καλός, kalos. However, kalos may and is also translated as ″good″ or ″of fine quality″ and thus has a broader meaning than mere physical or material beauty.
True beauty is the state of being authentic and sincere in a way that extends love to yourself and others. It feels real, safe, alive, playful, flowing, authentic, life-giving. This truth doesn't mean that beauty never has anything to do with our clothes or hair or bodies or faces.
