Jeans are such a wardrobe staple, I bet you have at least five pairs in your closet right now. So why buy another pair of denim jeans this season? Because you already know you're going to wear them religiously and these seven pairs are an easy and stylish way to update your wardrobe.

As you already know, jeans are machine-washable. You don't need to wash them everytime you wear them, and, in fact, most experts recommend that you don't. To keep denim jeans in the best shape, wash in the machine inside out and tumble dry on low.

Not sure what footwear to pair them with? Check out this list of the best flats for fall.

1. Colored Jeans

Who says jeans have to be blue? Or even black for that matter. This season's hottest jeans come in a range of colors from purple to emerald green to yellow. My pick is red, because it's the most neutral and therefore versatile of the bunch. (See how Rachel Bilson recently styled her pair.)

These J Brand 811 jeans are fitted from hip to ankle and with a slightly higher rise.

Available in sizes 23-32.

2. Jeggings

If you don't already have a pair of jeggings (denim leggings) these area  must buy for you. The Gap 1969 Knit-Waist Zip Legging Jeans combine the best of a legging and a jean. They are form fitting and you can wear them like you would a legging with oversize tops and sweaters, yet they are sturdy like a jean. These have a knit waistband and faux zip-fly front, so they're extra comfy.
Available in sizes 00-20.More »

3. Skinny Jeans

The skinny jean is like a jegging, but has an ever-so-slightly looser fit. The Skinny from Joe's Jeans comes in an edgy gray wash. These are perfect for tucking into boots, but look equally good with high heels and flats.

4. Flare Jeans

If you're a Boho girl, these slim flare jeans from Old Navy are the pair for you. The cut is a modern take on 70s bell bottoms: thin through the hips and thigh and flared from the knee down. Pair with a peasant top blouse or a fitted turtleneck sweater.
Available in sizes 0-20.More »

5. Boyfriend Jeans

Like the skinny jean, the boyfriend jean is going nowhere fast. With its lose fit and faded wash, this is the most casual of the bunch. The Levi's 501 Boyfriend jean is made for weekend running errands and, because they're so comfy, are great for wearing on long car trips or on a plane. Wear with a wedge heel to keep the look feminine.
Available in 24-31.More »

6. Trouser Jeans

The most formal of all jeans, and therefore most appropriate for the office, are trouser-style jeans. You can wear these Lucky Soho Trouser jeans just like you would wool slacks. Try topping with a blazer or a button-down blouse for a chic, pulled together look.
Available in sizes 24-34.More »

7. Black Jeans

Like black pants, black jeans are universally flattering and go with just about everything. The Gonzales denim jean from the Hudson Georgia May collection (created by Mick Jagger's daughter) are destined to be your Saturday night go-to pair. These have a sexy zipper up the side of the leg for added flair. Bonus: the horizontal line makes legs look extra long.</p>
