From the bottles the 2 colors I´m comparing today actually looked a lot alike. Well, the only thing that is the same is the finish and also that they are both blue.
LA Girl Punk is much darker than Gosh Blue Monday. I have to say I prefer Punk. Punk also has a slight purple duochrome which I couldn't capture unfortunately. Blue Monday in my opinion is better used as a layering polish, since it wasn't opaque in 3 coats and I'm not sure if it would with 4. Punk could have gotten away with just 2 coats, but I used 3.
Well, here are the pictures.
Index and ring = Gosh Blue Monday
Middle and pinkie = LA Girl Punk
Thanks for watching!
