As you know, I bought a huge bunch for polishes while in the UK, and when I got back home, I found out that 4 polishes looked like some of the ones I had before.
1. L'oreal 404 - Scarlet Vamp vs. Models Own - Red Red Wine
2. L'oreal 406 - Burgundy Diva vs. Models Own - Magenta Pearl
3. H&M Coral vs. Miss Sporty 452
4. 17 - Midnight Sapphire vs. Misa - A Sin Worth Commiting
So lets take a look at nr. 2. Burgundy Diva, and Magenta Pearl.
On this picture, you can actually tell that they are not a dupe, but in sunlight, they did look the same.
Wearing, from R to L:
L'oreal Burgundy Diva, Models Own Magenta Pearl, L'oreal Burgundy Diva, Models Own Magenta Pearl
L'oreal Burgundy Diva is a one coat color, with a C-brush. Easy to apply.
Models Own Magenta Pearl is a thin polish, great for layering. I used three coats on the picture, and it darkens ever so slightly for each coat.
Since it wasn't a dupe I though it would be a nice thing to do some nail art over it, to make it up.
I used Barry M - 302 - Fushia.
