Comfy things to wear around the house?

I got these amazingly comfy pajama shorts I found at Walmart (secret treasures knit shorts)

However, they are out of my size online and at the 3 stores I've been to in my city. Its getting a hassle to wash them every single day lol. I'm 34 weeks and just want to be comfy.

What are ya'll wearing? Its 500° here so I'm trying to find breezy things without wearing gowns or anything like that.

I'd prefer something more casual looking than pajama looking (plain colors are good!)
