I told my mom to stop wearing a wedding dress to family gatherings.

My parents got married about 8 months ago, and my family(3 sisters and 2 brothers) gets together like every weekend. My mom is a total vibe and has been wearing the white wedding dress to every gathering. My dad doesn't like it and it makes him feel embarrassed but she doesn't listen to him. She even wears it to church when we have to go. I told her straight up "mom, you can't wear that shit no more, it's so weird. " She started crying and said "I'm just trying to find my happiness." Like wtf. She's in her early 50s and has been acting so weird recently.
