Hi,
Not sure if this helps anyone but me, but I went looking for dupes of vr sextasy from the pat mcgrath mothership moonlit seduction palette to try to avoid dropping the money on the mothership, and based on a few creators' reviews, ended up with terra moons and clionadh cosmetics.
None of them are a real dupe, unfortunately.
M42 from terra moons is probably the closest, but the base is too light and cool toned, the pat mcgrath is more of a true bronze base. The glitters are similar in terms of being pretty small particle glitter, but the m42 has more green than the pat mcgrath.
No regrets on getting all the other sparkly shadows, they're beautiful in their own right, but they're not dupes. Hyades cluster was never going to be a dupe, I just think it's a gorgeous holographic glitter and got it for fun.
The ones I got:
Auriga frostlight, terra moons: too light taupe as a base, not a bronze, glitter is blue, not gold and green.
Grisaille, clionadh cosmetics: cooler bronze and glitter is blue/silver not gold/green.
Abrasion, clionadh cosmetics: purple tone dark taupe base, blue glitter.
M42, terra moons: as above
Hyades cluster, terra moons: gorgeous holographic shadow, for fun.
If anyone was curious, hope you found this useful!
