Hiding Ornaments And Ornaments Not Making Any Sound
The Quran says: And tell believing women to restrain their eyes also and to guard their private parts and to display of their embellishments only those which are normally revealed (24: 31) “Only those which are normally revealed” includes the things you mentioned.
As told earlier embellishment on bosom area should be covered. Same goes for ornaments on the parts adjacent to private parts like thighs etc.
