I know there were popular in the 70s, but wasn't that to loosen the fitting around the area to make it roomy or something? I know those were very popular to all age groups when we were growing up and that kind of did went into effect in the 80s-90s, but that was like a belt around the crotch region, correct? Curious to know.....for those that remembered these things. I am sure we had grandpa and grandma telling us "Well, back in my days....we worn things that didn't look like the ones you are wearing now!" But, anyway....just wondering about that.
