Courtesy of the shirt I'm wearing this morning, I had that thought that in the 80s we purposefully bought extra-large clothing because that was the style then, whereas today I have to buy XL in clothing so my shirts are long enough to cover my belly button (because no one wants to see that at work, and it's a safety thing).
The huge 80s clothes thing is also funny because I can still wear those shirts--and they're still huge on me now.
