I don't own Club e/s by Mac but just by looking at swatches online I can tell that these are both pretty similar. Also a dupe for Mac's Blue Brown pigment, Urban Decay's Lounge, and Too Faced's Label Whore. Here's a closeup of the ELF Natural Lashes, so not natural but I love them!
What do you guys think? I'm hoping to collect more duochrome shades because they're just so much fun to work with.. Do you own any or recommend any? Thanks for reading :)
