I noticed J.Lo and Sienna Miller sporting this specific color with flares—it's set to be a major trend this summer.
If you've been following the latest fashion trends, you may have observed that certain colors are particularly popular in 2025. It’s no surprise that butter yellow is very much in vogue and that chocolate brown continues to be a favorite. While I have incorporated both hues into my wardrobe, I’m particularly drawn to the soft, elegant, and summery baby blue shade. This tranquil color fits seamlessly among the beautiful tones that characterize summer outfits, and it has recently found a place in some of the most stylish closets, including those of Jennifer Lopez and Sienna Miller. Both stars have showcased the same pastel blue piece, but it wasn't just the color that stood out to me; it was how they styled it for the season. Instead of pairing this hue with just any outfit, both Lopez and Miller centered their looks around one essential pairing: a baby blue jacket worn with flared jeans, resulting in an attractive early summer outfit.
The jacket in question—Chloé's pleated jacket (£2,180)—features multiple pleats, giving it a voluminous appearance, complemented by its cropped cut and sleek single-breasted style. Embracing the elegant and dreamy vibe, Lopez styled her Chloé jacket with high-waisted, flared jeans in a deep blue, accented with soft pink and lilac touches throughout her bag, shoes, and blouse, creating a captivating color palette. While this combination feels strikingly contemporary, Miller actually showcased a similar look back in September at Chloé’s spring/summer 2025 show, teaming it with blush suede flares, oversized sunglasses, and layers of bohemian jewelry—indicating that this trend has been gaining momentum just in time for summer.
With two of my style icons already endorsing the blue jacket and flares look, I anticipate that this sophisticated combination will soon become widespread. If you’re also inspired by this rising trend, keep scrolling to find the best blue jackets to consider this season.
