These cute fall fashion trends are on sale for under $25 at Old Navy

Olive green is a color you're going to see everywhere this fall, so go ahead and start adding it to your closet now. This puff-sleeve top looks great with jeans (pictured here), but you can also dress it up for work by pairing it with trousers or a pencil skirt.

In addition to trendy green, the blouse comes in black, white, light blue and red. And at just $8, you can afford to buy one of each.

I love a flowy top, especially one with a fun pattern. This black-and-white print looks cute with jeans (both light and dark finishes) and you can easily throw a blazer over it on colder days. It also comes in a neutral shade and a bolder pink-orange hue. 

Reviewers note that it fits well on many different body types. "Such a pretty top. Flowy and flattering on a plus-size girl," wrote a fan. Added another: "I love the bigger sleeves and the shirt is a great length — not cropped but not too long!"

Business casual doesn't have to be boring, you know? Take this $16 steal, for example. While it's work-appropriate, it's still interesting and on-trend thanks to the square neckline, midi length and warm bronze color. 

This dress is truly a closet staple — wear it to the office with a blazer and pumps or add big earrings and a high ponytail for dinner with friends. 

The cropped flare pant has been a popular denim trend for months and now it's made its way to athleisure as well. These 60%-off leggings are great for working out — they have moisture-wicking technology built in! — but you can also wear them beyond the gym. 

Pair them with an oversized button-front shirt and your favorite slide sandals for a comfy weekend-errand-running outfit.

Cargo pants are controversial — some say they're fab and flattering, while others argue they look good on absolutely no one. If you're ready to take a chance on the silhouette this season, follow my lead and add this chino style to your Old Navy cart while the price is right.

Available in green, brown and gray, the high-rise style is slightly baggy in the leg and hits right at the ankle. You can wear them with sneakers for a more casual look or make them feel a bit more dressed up with ballet flats or ankle boots.

Blazers are always at the top of my fall fashion shopping list. They elevate any outfit and make you look more polished and put together. I particularly love this style for its notched lapel and single-button closure — you can score it right now in gray, black or navy for 60% off. 

More than 1,300 Old Navy shoppers give it five stars. A fan said it has a "great fit and looks good over any style shirt or blouse," while another added that it's "very well made."

Are you one of those people who lives for light jacket season? You know, when it's not super hot anymore but also not cold enough for a full-on coat? If so, check out this chic denim number. The longer silhouette makes it feel more sophisticated than a traditional jean jacket and the darker wash is perfect for fall.

Shoppers at Old Navy are already giving this utility jacket rave reviews. It's racked up more than 250 five-star reviews, with one person calling it "So freaking cute!"
