Doesn't Jaune Trendy look more mustard yellow like that, as compared to when it's on its own? :p
Below is a side by side shot. Feel that Jaune Trendy is more toned down and still wearable to office (if the environment is not too strict), while Little Miss Sunrise is brighter and more in your face.
In any case, they are not dupes and although I didn't think I was a fan of yellow/orange polishes, I really enjoyed wearing them :)
Thanks for viewing!
