I've tried a ton of MAC reds, and after careful consideration, I have to go with Scarlet Ibis. Lady Danger is very similar and also striking, but it doesn't always look quite as good on me. I've used Ruby Woo for years, but Stila's liquid lipstick in Beso is very similar and I've started to prefer it. Russian Red is popular, but I never liked it on me. I used to love Dubonnet and may repurchase it some day.
