Indeed, I wear one around the house quite often. Though this time of year, it's usually combined with some worn-out pants as leggings, and a plaid shirt or a robe on top.
Happy new year! 2024 had quite a lot of opportunities for me to wear a loincloth out in nature, and I'm already longing for the warmer months of 2025. At this time of the year I wear one only in my home, and with a t-shirt or somesuch — would not want for the heating bill to go through the roof.
