Reese Witherspoon can't stop wearing this classic top — get the look starting at $20

This cotton-blend shirt is sure to be a hit with those who prefer an oversized look. Slouchy in a stylish way, this button-down comes in more than 20 colors, including five white and blue options. If you prefer a more fitted look, grab one size smaller than your usual.

One shopper raved: "I LOVE THESE BLOUSES and am ordering more. The fabric is a soft yet crisp cotton. The collar, which I like to wear popped up, holds its shape. The blouse looks great tucked in, worn as a tunic, or as a lightweight jacket over a tank top." 

From the chest pocket to the wider stripes, there's a lot to love about this button-down. However, the best part has to be that it's wrinkle-resistant, so you can skip the iron. Available in sizes XS to 3XL, this shirt looks just as cute tucked in and buttoned up as it does with rolled sleeves and layered over a tank.

"The shirt fits perfectly, is ready to wear straight out of the dryer, and I always get compliments on it," wrote one reviewer.

This shirt is 80% cotton, so that means it's sure to be soft, super breathable and last for seasons to come, which is key considering how many ways you can wear it. Pair it with slacks for work, and on the weekend with shorts or even to the pool tossed on over your bathing suit.

One fan exclaimed, "GET THIS! It is bright and crisp and great with white pants, shorts, jeans or a skirt. I ordered XL to guarantee a flowy look and hide my stuff."

Quince's 100% cotton shirt is our top middle-of-the-road pick for its price, durability and quality. It comes in seven colors, and after we snag this blue and white one, the pretty peach shade is next on our wishlist.

One shopper called the shirt "perfection" and added, "This is the second time I’ve purchased this poplin shirt, and I can’t say enough good things about it. So comfortable, perfect weight fabric and looks so polished."

If you love a shorter hem, then this pick is going to be right up your alley. This drop-hem style hits right at the waist, making it extra flattering for those who are particularly petite or hate tucking in a lot of extra fabric.

One shopper gave this shirt five out of five stars and added, "It's pretty and I'm so glad it's designed for women. Men's shirts don't fit well like this."

No one does a classic button-down quite like J.Crew, but we love the extra feminine vibe this design has, thanks to its subtle lace collar detail. From the true-to-size fit to its classic silhouette, this shirt is definitely worth the investment. Plus, it comes in classic, petite and tall lengths, so everyone can find a perfect fit.

"Loved this beautiful basic. The lace collar is so pretty, not gaudy or cheap-looking. Fabric and cut were perfect for me," shared a satisfied customer.
