e.l.f. dupes/alternatives for Chanel, MUFE, etc. (from Wayne Goss)

In this short video, Wayne Goss favorably compares the e.l.f. Long-Lasting Lustrous Eyeshadow (which I posted about here - I also have the bronze one) with Chanel Illusion D'Ombre Long Wear Luminous Eyeshadow. He also recommends the e.l.f. Lock and Seal (which I used here), pointing out that it's exactly the same as versions from Make Up Forever and other brands that cost 5-6 times as much.
