This was the first MAC lipstick I had ever purchased and it still remains my favourite!
Ruby Woo has amazing pigmentation which flatters any skin tone and if you want a show-stopper colour, now you have it. I will say that the Matte formula is a bit drying after a little while so I'd recommend a lip balm or vaseline to be used before applying the lipstick but that's a small inconvenience compared to how long it lasts for on your lips.
MAC Ruby Woo is the ultimate red lipstick which screams for attention while still looking classy making it a wonderful investment for your makeup bag.
