Found this awesome website called character.com.
They sell mostly kids clothes, however they have T-Shirts and PJs for men and women with characters on. Most of the time these are characters aimed at adults/teens or all ages. Such as Harry Potter and Star Wars.
But they do a “mini me” range. This is a range of PJs that coinsides with their kids range, so that parents and kids can have matching PJs.
They do Peppa Pig and Hey Duggee. I was thinking of buying the PJ sets for the tops and wearing them as Tshirts. I would keep the PJ bottoms for sleeping in. But I definately think I could pull off the tops as daytime Tshirts.
Heres the Peppa Pig one:
