Should I get it or is it bad luck???

I know some people say it's bad luck to buy baby clothes, but I really like this onesie. We just started TTC and I wanted to have this incase it ever happens...like to surprise him when he comes from work with this and the BFP test. Some people say it's bad luck but I also feel like it's a positive sign of hope...ya know like speaking something into existence. And it's just one item, I'm not buying a whole wardrobe... What do you think? Any opinions? Should I get it, should I not? 🤔
