So today I have two Sinful Colors to share with you guys. I found these at Rite Aid and the whole collection seems to be like OPI Pirates of Caribbean dupe. I should look more into Sinful Color polishes. They are decent priced and the formula is not bad at all.
Adventure Island is a yellow green creme. 2 coats
Seaweed is a murky green creme. 2 coats
Seaweed looks quite similar to OPI Skulls & Glossbones except Seaweed has more green to it than Skulls & Glossbones. They're not exact dupes that's for sure.
As I mentioned, Sinful Colors formula are pretty good. I didn't have any issues with these two. They applied well, and was opaque in two coats. I hope they come up with more great colors in the future!
