My reminder is tight shirts and too small pants. Pre COVID all my clothes were fits. Not now 🙈 I can't wear my old shirts, they're way too small and I can't breathe while wearing them.
Also when i sit my newly belly roll gets pinched on the belt buckle. Never happened before.
One for me was getting too fat for any clothes at Wal-Mart. At the time it seemed like I moved straight from from 2XL to 4XL. By the time they actually had a few 4X items, I was already near 5X. Now I don't even bother looking even at Big & Tall places. I also have to leave early to go places so I don't show up sweating like a hog. I still sweat of course, but not badly enough that it looks like I ran there with a soaked shirt.
