My daughter literally hates to wear undershirts inside home but is forced to wear it when she goes outdoors. Now, I am worried about what the society will think if she refuses to wear undershirts in home(and outside). So I am trying to force her to get used to these. But now she's getting separated from me so I asked her grandma to try to convince her. She tried to intrigue her and make her wear them by using words like "shameless" etc. Still she refuses to. What can I do?
