The first red lipstick I remember as being truly life changing for me was MAC Russian Red, which I purchased in 2007 (my sophomore year of college) at the behest of Dita Von Teese. It's a super matte vintage red cousin of Ruby Woo and my mom told me once that Russian Red did not suit me. I didn't care. I wore it every day, everywhere, all the time. Red lipstick became My Thing.
Over the years and many trips to Sephora, I've actually tried all the lipsticks mentioned here! And I've learned that I prefer a satin formula (not matte) in a bullet tube (not pencil or liquid). My favorite lipsticks are now Revlon Super Lustrous in Pink Velvet (a warm pink that pulls reddish on me, subtle and perfect for daily casual wear) and Guerlain Rouge G in 214 Le Rouge Kiss (a warm fiery satin red that comes in a customizable, refillable case with a mirror and the option to have your initials engraved, which of course I did).
Every once in a while I'll play around with other formulas and shades, but for several years now I've always consistently come back to these two. They're perfect and I love them so much.
I never feel completely dressed unless I'm wearing lipstick and perfume. To me they are essential accessories and no outfit is really complete without them. I suspect Taylor would wholeheartedly agree.
