Lipstick is arguably the most beloved item in our beauty arsenal. Few things have the power to completely transform our look in two seconds flat. Plus, there's no denying the importance of a product that was once supposedly worn by George Washington, and also used to indicate whether or not a woman was a prostitute .

These days, the biggest problem we have with lipstick is figuring out which color to wear or how to stop buying so many tubes (answer to the latter: it's impossible). Thankfully, there's an endless feed of lipstick inspiration at our fingertips: Instagram.

Whether you're looking for the perfect rose-pink shade for your upcoming trip to Dubai or just feel like perking up your mood (and look) in a classic red , there is plenty to pore over on the social media platform.

With that said, in celebration of National Lipstick Day on July 29, we've rounded up some of the prettiest pouts on Instagram, showing you where you can find each eye-catching color. Muah!
