At #2: MAC Cosmetics Lipstick in shade Ruby Woo

This shade defines red. Every girl owns a red lipstick, but once you've tried Ruby Woo, you don't go back. The shade debuted in 1999 among a collection of various other colors that were eventually discontinued, but Ruby Woo has remained. A tried and true favorite, Ruby Woo is truly a cult classic that is known by women worldwide.

What makes Ruby Woo such a beauty bag favorite? The shade works universally on all skintones. Talk about versatility! The color of this lipstick is a blue-red hue that always compliments the wearer. Ruby Woo offers brilliantly rich color as well as a classic retro matte finish, so this shade ain't going anywhere. Its vibrant hue defines lips beautifully and goes on smooth for easy application.

Ruby Woo is truly a lipstick loved by all. From makeup gurus, bloggers, models, and Hollywood starlets, this little tube of color is the benchmark for all other reds. Some celebrity fans include Elle Woods, June Ambrose, Liv Tyler, Diane Kruger, and pop music sensation, Rihanna. Earlier this year, the divalicious star partnered with MAC Cosmetics and launched her own version of this cult lipstick classic called RiRi Woo.

Working with MAC, it's difficult to get a red lipstick that beats Ruby Woo, because it works on every skin tone," Rihanna said.  "I had so many different samples to choose from and so many different colors underneath - blue, yellow, orange and pink bases. And I got to pick one that worked," Rihanna explained. RiRi has big lips to fill with her version, but the original isn't going anywhere.
