General

I'll cast the vote/opinion in favor of underwear.

When I sit down, I actually do feel my gut on top of my thighs, and it's slightly less comfortable if I don't have the underwear that's in between.

Chub rub is also quite real, and certain types of underwear definitely help with that. Also of course, the possible risk of various bodily fluids being more likely to soak into the regular clothes if there is no underwear, despite one's best efforts. That's probably at least 99%+ of the reason behind underwear in the first place.

It's certainly nice to sometimes sleep without wearing underwear, however.

I’m most comfortable at home stark naked.

I always wear underwear with clothing, though.

Whooaaa - the thought of you sans underwear and at 420 pounds is incredibly hot.

I prefer just underwear around the house. Most of the time with a shirt, except in summer. But I’ve noticed if I wear just that, and maybe some stretchy gym shorts, when the time comes to wear pants again it almost feels like I’ve gained a size or 2, until I’ve worn them a few days and either they stretch or they move around the fat and they feel fine. Lol

I agree 100% although I occasionally wear just underpants I usually wear loose 3XL shorts come summer or winter. I do have elasticated waist denim jeans if I'm going out more than just shopping.

T shirt and cotton gym shorts are my preferred stay-at-home attire. Occasionally I’ll go without skivvies (boxer briefs) under the shorts. Sometimes I wear just skivvies. I always wear skivvies to bed, usually w/ a t shirt.

for me its only underwear in the summer and underwear and a thight but stretchy shirt in the winter

I find clothes restrictive and when home I go naked unless too cold.
