"I DON'T EVEN KNOW WHAT TO DO!"
That's what I hear when people are looking for a lip color that would look best on them. What may work for Kim Kardashian may not work for you. Personally, I feel women can wear any color lipstick but you have the find the exact shade that matches your complexion. I found some cheat sheets for you all. I understand that there are different spectrums of each shade category but this might help you. For example they use Beyonce Knowles as medium skin tone, but you may be medium but slightly tanner than her. Try to use what they offer as a starting point. Here is the link to the original article.
Sometimes my bestie and I have this look when we see women with random lip colors on (we are makeup snobs lol). We try to help out but some ppl set in their ways lol smh.
