There's a jean sale in almost every store and boutique this October!

Every year, we can look forward to marked down prices on jeans, even before Black Friday deals.

But wait, before you rush to Levi's and Old Navy, check out our guide on the latest jean trends this fall and how to wear them. Oh, and we'll throw in our scoop on where to shop for the lowest prices on a pair of denim jeans!

Boyfriend jeans? The Roomier the better!

Channel your inner Gigi Hadid and wear high-waisted baggy jeans with a metallic top and pointed stilettos.

High-waisted boyfriend jeans are also a must for beauty mogul Kendall Jenner, who went for the oversized jeans trend with knee slits and paired it with a knit crop top to show off her toned abs.

Jenner's best friend, Hailey Baldwin, also copped the trend and paired it with a crop white tee layered with a beige linen blazer, unbuttoned.

Give Your Skinnies a Break!

Fear not, the skinny jean trend won't disappear anytime soon; however, we're seeing stars walking out in a straighter cut.

Ankles are given a little more room to breathe with a classic jean style.

We've seen Jennifer Lopez trade her skinnies for high-waisted, straight-leg pleated jeans, coupling it with a classic white button-down and a little peek-a-boo.

For a modern take on the '90s jeans, we like General Pants Co. Their high-waist, straight-leg denim paired with a bodysuit and booties make the perfect look for a night out in the city.

Flares are Back, Now with Side Slits!

Penelope Cruz had a flashback of '70s style with a light-wash flared jeans highlighted with a modern twist. She opted for a structured blazer in a bold red color, Chanel Cruise 2020 bag, and Chanel sunglasses.

Wide-legged flared jeans look great with your fave crop tops, too!

Fall trousers are wide!

Wide-legged pants put you in command amid a sea of skinny jeans. It has the lady boss look that you'll love.

Kim Kardashian West loves the snakeskin leather trousers from Off-White with a matching black Top by Tom Ford. She completed the ensemble with a snakeskin leather mini bag.
