The original OPI Hawaiian Orchid was a milky, semi-sheer orchid pink that made my nails look deliciously clean and healthy. I've searched and searched for a dupe. I don't know when OPI updated their formula to a slightly coral shade, but changing perfection is a no-no and should be outlawed.
I wish they wouldn't change what's perfect,if they're going to continue producing a colour. I'd guess there was a problem with getting the pink pigment. But I would have just discontinued the colour, in that case.
I don't even know which colour you're talking about, so I don't have any dupe reccs. But I wish you luck in finding a dupe that you end up loving!
Do you know when they changed it? I have a bottle that’s a few years old, would be happy to mail it to you if you cover shipping. It’s at my ex's so it’ll take me a little while to get over there, though
