The waistlines of girl's jeans has lowered to levels not seen since the early '70s, which, I believe is because of retro fashion being the style of choice nowadays. I guess it could create some functional issues when the pockets in your jeans are 1" away from the top of the leg, and the waist is only 3" away from the crossroads.
What happened to jeans with the waistline just below the bellybutton? I thought they were so much better looking on a female shape,.. they amplified the curve at the hips,.. created some vertical shape to the rear,.. provided diametrical contrast between the waist, and hips,.. no muffin tops, dunlop's, or whale-tails with a higher waistline...(sigh)
I miss those styles from the late '80s, and early '90s... And now that it's summertime, swimwear too...
