Dupe Alert: SC See You Soon and NOPI Too Rich For You

I think the Nicole OPI Gossip Girl Collection came out in 2010, but I purchased Too Rich For You on sale at Walgreens. Earlier I posted (cuticle alert on that post!) that Nicole...Spotted was a dupe of SinfulColors' Nail Junkie. I think that it's not hard to see that Sinful and Nicole by OPI have another dupe in the mix.

Here is Nicole by OPI Too Rich For You:

Next up is SinfulColors' See You Soon:

Both are in a smoky black base that is loaded with a deep peacock blue shimmer. Neither fails in the application department: three coats, good dry time and nice wear. I think NOPI was more sheer at the outset, but by coat three, it was fine.

Here is a comp:

Another case of "cover the titling with your hand and see of you can really tell the difference." (<=good gravy, get Strunk and White already!)
I feel like these were bottled from the same vat they are so similar.

I think a bottle shot tells the story on their similarity:

In the bottle there appears to be some sort of duochrome action on the SinfulColors See You Soon, but on the nail I could discern no diffference whatsoever. It could be the NOPI bottle that masks duochrome, though, so I am not 100% sure that it's not there. Some help, right?
I found my NOPI on sale, about the same price or less than SC, plus the Nicole is currently  - by Google Shopping standards - much more expensive than SinfulColors' offering.

I admit in the blue family I love that maritime/peacocky/tealy sort of blue as much as my blue/purpley periwinkles. What am I saying here? I don't mind having two bottles! ;D

Thank you for reading my little nail polish journal!
