Can you say that you dont have/use pajamas, WITHOUT implying that you sleep naked?

My workplace has pajama day sometimes, where we are allowed and encouraged to come to work in pajama clothes.

I've never worn pajamas, and what that means has changed over time, but whenever I've told someone this they have assumed that it means either that I sleep in underwear or naked.

Neither of these would be appropriate to tell (or imply) to a coworker in response to a question about a fun event day. So, I'm wondering if there's some way to say it that would NOT imply the most likely alternative?

I don't want to make up some elaborate lie, I just don't want it to sound like an intentional innuendo. there's only so many times that I can say that I just forgot... Any suggestions?
