The exact shade of yellow nail polish Kim Kardashian has been wearing on Instagram

If you haven't noticed, Kim Kardashian and her sister, Kourtney, have spent the past week living it up on the Turks and Caicos Islands. We know this thanks to a barrage of Instagram posts from the pair, showing them lounging, swimming and generally relaxing. Of the holiday snaps, there was one post in particular that stood out: this picture of Kim's feet painted in a neon yellow polish.

The hard-to-miss yellow polish is a strong look and is a nod to '80s beauty—a trend that we saw quite a lot during fashion month earlier this year. The polish itself is surprisingly affordable. Kim's nail artist, Kimmie Kyes, recently revealed on Instagram that the KUWTK star was wearing Orly Nail Polish in Glowstick ($14.95 at GlamaCo).

We all know that Kim can afford the most luxe beauty products on the market; however, she often forgoes designer beauty in favour of more affordable brands. Earlier this year, the 37-year-old revealed via a post on her app that she uses The Ordinary's $18 Granactive Retinoid Emulsion 2%. She also loves the L'Oreal Paris Voluminous Mascara.

If Kim Kardashian is wearing neon yellow nail polish, does this mark the start of a trend? Time will tell.
