On a recent trip, having misplaced/forgotten my trusty MAC Whirl lipliner, I ran to the nearest drugstore to get as close a dupe as I could possibly find. I dug up Rimmel's Wild Clover, and while not exactly a perfect Whirl replacement, it was pretty enough, and based on all the reviews about its creaminess and longwearing capabilities, seemed worth it.
On my skin (NC25), it's quite vivid and pink. It looks a lot friendlier as a pencil than it does actually worn on my lips - it actually imparts too much of a Barbie pink shade than the nude pink everyone seems to get. Still, when blended and worn with a clear gloss, it's very pretty. Just not the nude pink I was looking for.
