I Found The Chicest Under-$100 Fall Workwear Staples at Gap

You don't need me to tell you that a button-down shirt is a workwear staple. Refresh your collection with Gap's top-rated option, which comes in eight other on-sale colors.

Gap's CashSoft line has all of the cozy softness of your classic cashmere sweater without the usual price tag and dry-clean-only label. This striped crewneck silhouette is discounted in multiple shades, including neutrals like grey and black and trendy colors like red, blue, and green.

A shirtdress like this is a quintessential workwear piece. It works for every season and can be styled up or down. I think it would look cool (and office-appropriate) with a pair of jeans and some kitten heels.

If Katie Holmes loves barrel jeans, then so do I. The star recently wore hers with a button-down and ballet flats, proving that the polarizing trend can be chic for the office.

As far as outerwear for the office goes, all you really need is a classic trench coat like this one. The age-old piece goes with any fall outfit you have on underneath.

Gap's 365 trousers are a fan favorite. Now that they're 40 percent off, I'd stock up on all of your favorite shades. Reviews say they're so comfortable thanks to the elastic at the back of the waistband.

This satin shirt has all of the styling possibilities of a cotton button-down shirt but has a more elevated feel. The chocolatey brown shade is so dreamy for fall, too.

Add a polo neckline to anything, and it instantly feels more professional. Coupled with the deep grey shade, this dress is practically begging to be your next office go-to. Wear it with knee-high boots and tights, and rest assured, you'll be comfy and cozy all day long.

I'm thankful that the tailored vest trend isn't going anywhere for fall. It's a style that screams "I mean business" from the get-go, so it deserves a place in your fall workwear rotation.

These slim trousers are great to have on hand for days you're in a rush. They're polished enough to wear with an oversized sweater and flats, and you'll still stay comfortable.

It probably has to do with Zendaya's Challengers press tour outfits or maybe the flood of US Open content, but I'm obsessed with the tennis-core aesthetic right now. It's a look you can easily pull off in the office, too. Pair this sweater with trousers and loafers, and you've got an outfit I know Z would be proud of.

We're still in that weird transitional period when it's hot during the day but cool during the mornings and evenings. This breezy blazer will serve you well for whatever the weather throws at you. The belt is removable, too, so you can get two looks in one.

I love having a sweater dress like this in my workwear rotation. They're a one-a-done outfit—I can throw on a pair of boots, grab my favorite leather tote bag, and head out the door.

Gap has really hit it out of the park with its sweater offerings this season. This cardigan is just one of many that I want to buy.

You must have a little black dress in your wardrobe no matter the season. This is your fall version—it's appropriate for the office and is the perfect base for getting creative with your shoes and accessories.

Now is a good time to take stock of your knitwear collection and refresh it with new colors and silhouettes. This cable-knit sweater comes in one of the season's hottest colors, grey, and has a slightly cropped hem that pairs nicely with your high-waisted trousers, skirts, and jeans.

The contrast stitching and exaggerated ribbed cuffs on this luxe-looking sweater give it an elevated feel. Do yourself a favor and see how Gap styles it with the matching scarf and knit skirt—obsessed is an understatement.

This denim skirt is office-appropriate and can be worn with pretty much anything. It'll effortlessly take you from morning meetings to after-work happy hour, too.

Thin with a relaxed, easy fit, this turtleneck will be your fall wardrobe's hero piece. You can wear it under all your coats and jackets, or on its own with a skirt. Trust me, this is one piece you'll wear time and time again.

The next time you feel bored with trousers and jeans, switch it up with this pair of corduroy pants. The fabric feels very on-brand for autumn, and this burgundy shade is one of fall's top trending colors.

Don't mistake this for your run-of-the-mill T-shirt. Gap's basics are amazing in the quality department, and a few details make this tee stand out. It has a super soft feel. It also has longer sleeves and a higher-cut neck for a more luxurious look.

Animal prints of all kinds are trending for fall, but cheetah print is the most popular with the fashion crowd. Wear this skirt with a sweater for a simple yet elegant outfit that works for the office and beyond.

Slim-fitting cardigans are having a moment. Take after the street-style set and tie your sweater over your coat or wear it with just the top button closed and a tank top underneath for a peek of skin. Gap even has a matching tank you can snag, which is also on major sale!

Even though we're approaching colder weather, you can still get plenty of wear of out this pretty $20 shirtdress. Wear it now with your favorite ballet flats and later with every type of boot you own.

If your office dress code allows for jeans, this is a pair you can definitely get away with wearing to work, as they have a much more polished look and a trouser-like silhouette.
