You'll want to get your hands on it ahead of spring.

My heart skips a beat every time there’s a mini Big Little Lies cast reunion, so when I saw Reese Witherspoon wish Laura Dern a happy birthday on Instagram, I fangirled hard. As I basked in the snap of the two sitting side-by-side on a low-key coffee date, one small but effective detail in Witherspoon’s outfit caught my eye—because it's a style hack I swear by. Peaking out from under a baby blue V-neck sweater, she wore a crisp white T-shirt.

Sure, you don’t always have to put a base layer under a sweater, but that simple addition instantly makes an outfit look so much more put-together, on top of adding warmth for early spring days. Her post reminded me that I’m due for a restock (I’ve been styling Abercrombie’s the same way on repeat), so I rounded up a variety of seven options from $8, below.

This affordable basic from Hanes is the gold standard for a reason. It features durable stitching, a stretchy crewneck collar, and a non-see-through cotton fabrication that makes a great breathable layer in any weather. Consider it the ultimate outfit building block. For only $8, it’s a no-brainer.

I find that some of my sweaters and crewneck sweatshirts have too thick of a collar to allow my white neckline to pop out. Trendy Queen’s stretchy, slim-fitting tee solves that dilemma, thanks to its high-cut neckline. It’s racked up over 2,000 five-star reviews, with one shopper saying it “looks great under a sweater or vest without adding bulk or heat,” and added that it feels “soft” and “silky.”

GAP Factory

We’re not at the finish line of winter quite yet, so a long-sleeve tee is a great option for the same effect with more warmth. Gap Factory’s Ribbed Long-Sleeve Crewneck T-Shirt is 50 percent off right now and has a cozy ribbed knit fabrication that adds a little more texture to the simple style. Plus, you can shop it at the same discount in more spring-ready color options, like sage green and pale purple.

Below, shop more white tees under $20, including a now-$12 mock-neck style and my favorite relaxed silhouette from Abercrombie that I wish I ordered at this discount.
