14 Fashion Rules Jennifer Aniston Lives By

Jennifer Aniston is one of those stars who rarely misses the mark when it comes to fashion. Her leggy, red carpet dresses consistently turn heads, her jeans and T-shirts always seem casual-cool, and her go-to wedges have sent us on our own personal shopping sprees. In short, the Emmy award-winning actress's style can't be beaten — and even the looks she wore in the '90s serve as modern-day outfit inspiration.

Part of this is because when Aniston likes something, she really likes it and wears it on repeat —sometimes even for decades. Looking back at the Friends alum's best fashion moments, we've realized that she sticks to the same styling hacks and tricks, which we've rounded up, ahead.

Invest in a Pair of Wedges

While some people love white sneakers or sexy stilettos, Aniston's go-to shoe is a pair of wedges. She's been wearing this style for years, breaking it out for both casual outings and red carpet appearances, and convincing us that these babies pair well with everything.

Go Beyond Your Trusty Denim

Jeans are cool and all, but according to Aniston's outfits, olive green cargo pants are worthy competitors. They're still neutral and versatile and look great with all the basics in our closet — but they add a slight pop of color.

Leather Isn't Just For Jackets

Many of us have motorcycle somethings tucked away in our closet, but the actress is a fan of leather dresses and pants, too. (A little ode to her onscreen love, Ross Gellar, perhaps?) She even wore a longer, duster-style jacket back in the '90s, making quite The Matrix-y statement.

Hats Will Give Any Outfit a Boost

Perhaps she's hoping to avoid the sun. Maybe she's shielding herself from prying paparazzi. Or maybe Aniston just knows a fedora can give casual outfits a little extra oomph. She frequently gives her look a laid-back, boho vibe with this type of addition, and over the years, has developed quite the hat collection.

Scarves Work For Every Season

While a scarf is no doubt a practical accessory for winter, a lighter version can make summer outfits more interesting. The actress is known for pulling this styling trick since her Friends days.

Find Your Signature Fit

Sure, Aniston loves a boot-cut jean, but she also has a ton of baggier pants in rotation. When she opts to wear boyfriend jeans, she keeps her outfits simple and slim-fitting on top, playing with proportions. Plus, as the pictures show, she cuffs the bottoms and lets her ankles peek out — a classic, elongating trick.

Stock Up on White Tees

It's hard to think of an outfit that won't work with a white tee. This staple looks great with denim, skirts, sweats, and suits. Plus, we'll never forget when Selena Gomez embraced the '90s Friends style and layered one under her jumpsuit.

When in Doubt, Grab a Button-Down Shirt

Of course, when a T-shirt seems too casual for what you've got going on, a button-down shirt can easily take its place. The Morning Show star has worn her fair share on the red carpet and occasionally goes for an all-black look, which is always super sleek.

A Structured Blazer Is Extremely Versatile

Every so often, we face the same dilemma: what kind of jacket to wear when denim doesn't work — leather seems too casual, and the weather's too warm for something furry. The answer is a blazer, one of Aniston's favorites. She has used a blazer to make simple pairings seem more polished, and has even worn it over fancy dresses.

String Bikinis Are the Ultimate Vacation Staple

Nothing gives off vacation vibes like hitting the beach in an itty-bitty string bikini. This swimwear is versatile and sexy, making it forever stylish — no wonder Aniston is a fan.

A Black Crossbody Bag Makes a Great Everyday Option

Stylish and practical, black crossbody bags are a constant in Aniston's accessory collection. Not only does the color mean you can reach for it any day of the week, but it's also easy and hands-free for those of us who are always on the run. Take another tip from the star and go with a safe, medium size so you can fit more stuff.

Pendant Necklaces Make Any Outfit More Interesting

It's pretty much guaranteed that if you find the perfect pendant necklace, you'll start pairing it with all your outfits, from the office-appropriate ones to your throw-on-and-go looks. The Murder Mystery co-star is a prime example of this.

Aviator Sunglasses Are Timeless

Despite the different sunglass trends that are out there — tiny sunglasses, cat-eyes, etc. — aviators continue to remain Aniston's favorite. They're universally flattering, never go out of style, and give off an edge. You really can't go wrong.

Long Black Dresses Work for Any Fancy Occasion

For those who have a ton of weddings and formal events on their calendar, do as Aniston does and make sure you have a long, black dress handy. This no-fail option has helped her rule the red carpet for years, and, for us normal folks, it can always be worn again.
