I haven't been on the nail scene for that long. My obsession started last Novemberish and at that point I only had 9 polishes, all of them different shades of pink. So, please excuse the fact I never had a bottle of the original GOSH Holo.
However, life is kind and they re-released GOSH holo and all my chicks came home to roost. Then, last week I popped into boots to have a peruse and No17 had its own holo on offer, and I couldn't resist but give it a go.
In the picture at the top of the screen I have mixed the fingers I have put each polish on my Index finger we have GOSH Holographic, my Middle finger is sporting No17 Holo, my ring finger has the GOSH and my pinkie the NO17.
There are some more pictures below. They are clickable if you want to see them larger.
For application I used a matt topcoat as a basecoat, Two coats of the polish, another coat of the matt topcoat and then a final application of the polish.
The results are startlingly similar. The bonus being the No17 I had applied much better. It was smoother and more opaque in its application. It was also less streaky. Oh, and its cheaper. £3.99 a bottle, but at the moment in boots its on 3 for 2 - bargain!
