Yves Klein Blue Is Spring’s It Color—and This $48 Aritzia Top Is Perfect

One of my favorite parts of spring is adding a bit of color back into my wardrobe. And that’s coming from someone who basically lives in neutrals day to day—I’m firmly in the black, white, beige, and brown squad—but I can’t lie, I do love some pop for a standout moment. And the biggest color trend this season? It’s none other than Yves Klein blue (sure, you could call it cobalt blue, but let’s give the man his flowers!). We’ve been seeing the electric shade everywhere, from runways to red carpets. We even named it one of Cosmo’s spring fashion trends of 2026!

Need proof? Designers Willy Chavarria, Mugler, Valentino, and Isabel Marant all showcased the bold hue in their Spring/Summer 2026 collections— on dresses, tops, blazers, skirts, trenches, and more—proving just how versatile it can be. And when Sabrina Carpenter wore a turtleneck in the color for her Coachella Weekend One performance, that was basically my sign to start shopping.

So I went looking for an easy, affordable way to wear it that actually fits into my spring/summer wardrobe, and I found it: the perfect Aritzia top in the exact shade. Simple, wearable, and an easy first step into trying out the bold pigment.

I love that this top is an easy, wearable halter style. The silhouette is basically my warm-weather go-to because it feels a little more elevated than a tank, cami, or tube top. The neckline is super flattering, and it instantly makes even a simple jeans outfit feel more put-together without trying too hard. It’s made with Aritzia’s Original Contour fabric, which means it has that smooth, body-skimming fit. And for $48? I’m running to buy this!

I’ve got these cobalt blue tops on my radar, too. Shop them here:
