Help raise awareness of the world’s largest bodies of water and advocate for their wellbeing.

Any shade will do — aquamarine, cobalt, azure. If you’re really daring, opt for a splash of black-blue lipstick, like Hailey Baldwin did for the BRIT Awards.

For styling cues, look no further than these stylish celebs. Go the extra mile with a little bit of sparkle, which can nicely evoke sunlight or moonlight playing off water, as demonstrated by Oceans 8 star Mindy Kaling in midnight Prabal Gurung, Susan Sarandon in glistening Alberta Ferretti, and Mandy Moore in shimmering Ralph Lauren.  — jas
