Mom said it’s bad luck to buy baby clothes?

I’m 13 weeks. I want to buy baby clothes for my baby girl cause I just want to! They’re so cute and I’m excited to build her closet. My mom told me not to cause it’s bad luck cause “you never know what could happen” and then I’m just stuck with all this stuff. This makes me feel so sad I just want my baby to have cute clothing that I want to dress her in 😭 but now I don’t know….
