Jeans are a type of pants or trousers, typically made from denim or dungaree cloth.
It is not allowed for a Muslim woman to appear in front of Non Mahram men with out full Hijab covering all her body and hair.
Full Hijab means covering all her body and hair with cloth which must not be tight nor transparent.
The purpose of hijab is modesty and decency. The means of doing that is left to the individual, rather than specifying that certain clothes are allowed or unallowed, especially because what looks modest and decent on one person may look different on another, and fashions are always changing.
If you are asking regarding your daughters, perhaps you could talk with them about what appears modest and decent.
Regarding tights, it could be argued that they are not generally considered to be "clothing" in an outerwear sense.
Wearing clothes that reveal the shapes of the body is not allowed for a Muslim woman unless the shirt is wide and cover all parts like a long jilbab or abayah.
With prayers for your success.
