Adam Clarke on Jeremiah 2:32

Can a maid forget her ornaments - This people has not so much attachment to me as young females have to their dress and ornaments. They never forget them and even when arrived at old age, look with pleasure on the dress and ornaments which they have worn in their youth.

Days without number - That is, for many years; during the whole reign of Manasses, which was fifty-five years, the land was deluged with idolatry, from which the reform by good King Josiah his grandson had not yet purified it.
