Ever since Co-Kate stepped out in her high-waisted trouser jeans, fashionistas couldn’t get enough. Take things to new heights with fall’s high-waisted trend in everything from skirts to jumpers to jeans and more. Get that pinup girl style with this curve hugging Earnest Sewn Maya High Waist Stretch Pencil Skirt (0). Or sex up the suspender look with Diane von Furstenberg’s Lizzy Jumper Dress (5). With a special tuxedo waist and kitschy suspenders, this jumper will become a favorite for every season. And for those casual days (bailing Pete out of jail in Kate’s case), these Topshop Wide Leg Jeans (£40) can be dressed up or down depending on your mood. Now everyone go get waisted!

Insider Tips: There are a few rules you must obey when treading in high waters. *Always tuck in your shirt…otherwise, what’s the point? The pants need to be fitted so try going blousy up top. *Don’t try to wear your mom’s from the ‘70s. Cuts, styles, and sizes are completely different these days. *Do get a size that fits. Too baggy looks dumpy and too tight…well, we won’t go there, and neither should you! *Add some flare. Wide-leg is the best look. You don’t want to look like the second grade nerd. *The darker the better! It’ll hide imperfections. *Always wear heels. Short and stumpy does not work with this look!
