Bad luck to still be wearing Christmas pjs?! in own home?

[Summertimesaddness]

I have some really comfy Christmas themed pajamas that I still want to wear at home. I've heard that wearing Christmas clothes after the Christmas period brings bad luck and I am just wondering if this is a well known thing or am I mistaken?!

I've heard of not singing Christmas carols after Christmas is bad luck but not clothing.

Please wear them all year! Or else they presumably go in landfill after December?! Daft!

That's just consumerist bollocks trying to encourage you to buy more stuff. Bad luck doesn't exist.
