In the late 80's, Princess Diana was all about her blue eyeliner. It was a subtle (yet impactful) way for her to break from royal tradition, adding a touch of personality to her makeup. Decades on, that stroke of aqua a long her lash line feels just as cool today. In 2025, it's all about the return of the blue hue; from Dua Lipa’s cobalt flicks to Zendaya’s cool navy lines, A-listers are embracing the same cool pop of this year. The runways have followed suit too, with designers like Victoria Beckham and Paul Castello sending models out in washes of cerulean and smudges of indigo, cementing blue eyeliner as this season’s boldest beauty revival.
Diana usually opted for a traditional vibe, which focused on applying the shade to the inner rim of her lower lash line, to make her ocean-toned eyes appear brighter and bigger. However, in 2025, there are many ways to use your eyeliner to make your look standout.
Today, we are using pencils to create classic cat eye flicks but rather than precision, many of us actually favour diffused or smudged finishes. This gives the eyes a slightly sultry effect rather than polished look. Beauty lovers are also using eyeliners for extreme designs, creating graphic lines and shapes to express themselves which we're also loving.
According to Princess Diana's makeup artist, Mary Greenwell, Diana's beloved blue eyeliner she used on her lower waterline was Elizabeth Arden's Blue Khol 636 pencil. Unfortunately, this shade is now discontinued but we've done some digging and have found the perfect alternatives that will brighten up your look for autumn. From inky pencils to liquid liners and kohl pencils, here are the best aqua-hued products to shop now.
