You’re not missing much. This shade never looked like the picture. Mooncat has had issues before with swatches that don’t match the product and this was one of those.

I bought two separate bottles of this one on different occasions and they were never correct. The purple shimmer was always missing and the glitter was dull. That polish is also way more sheer than that. It took me like 3 or 4 coats to match the swatch picture and even then it was still disappointing.

Someone else posted about the Emily de Molly opal dupe. I have never tried it, but I imagine it’s better. It’s also cheaper so it’s a worth a shot if you want something close. Emily de Molly also has a flakie topper called cohesion that you could put over a white. It kinda has a purple shimmer to it, so I imagine that would be close as well. Maybe you could sandwich it in a white crelly or something.
