I've heard a lot of people say that Revlon Pink Pout is an exact dupe for MAC Snob, and since I happen to have both colours I thought I'd do a comparison.
Side by side the colours look identical.
Swatched on my hand they also look pretty close.
However worn on my lips I can actually tell the difference.
While they're almost identical, Snob (left) is definitely more pigmented, and a cooler pink. I feel that I can't wear Snob when I have a bit of a tan as it makes my lips look too blue. For me Pink Pout is the summer version of Snob.
Have you got either of these colours? Do you think they're good dupes?
