I'm not going to claim dark lip tones as an invention of mine since most bloggers and youtubers are sporting them but I will say they make it look so much easier than it actually is. Make up stands are brimming with choice but it can be -it certainly was for me- overwhelming to be facing 4 different shades of red and not know which one would suit you. I'm afraid I don't have a secret nor a quick solution, it's a case of trial and error, but I do have a recommendation so maybe that will help next time you're in Boots and having an existential crisis in the makeup aisle.
