There is a takanas ezrah that peddlers sell cosmetics in towns so that Jewish women look pretty. Miriam knew that Moshe separated from his wife Tzipporah because she stopped dressing up for him (Yalkut).
So Jewish women ought to look nice and presentable. They should not be seductive, at least in public. That is what Yeshaya was discussing.
I hope that frum Jewish women today dress within those lines. Its not the details – the necklace or whatever – but the general profile.
