Nails Inc Gossip Girl Inspired NOTD - Chanel Black Pearl and GOSH Rainbow

I've seen quite a few posts over the last few days about the new Nails Inc Gossip Girl collection.  Basically, these are a nail colour with a sparkly, foiled over-glaze, sold at an eye-watering £20 for a set with the two polishes.  There are three colours to choose from, although I think they all look pretty similar to me!

I was reading Le Petit Jardin de Liloo's post on the new collection, where she mentioned that the over-glazes are very similar to Rainbow by GOSH (which is sadly now discontinued).  I do own Rainbow (I think I got one of the last bottles in the country), and I decided to use it to create my own Nails Inc Gossip Girl inspired/dupe nail look.

All the Gossip Girl colours are dark, in blue, black and deep maroon.  I don't own a pure black nail colour, but I do have Black Pearl by Chanel which is blackish/dark green/petrol, so I used this as a base colour.  I used two coats of Black Pearl and then put on a coat of Rainbow.

I'd not used Rainbow for ages and had forgotten how lovely it is - it has large flakes of foiled glitter in green, yellow and red depending on the light - you can see all the colours on the same nail.  It also dries smoothly (unlike some other foiled glitter polishes) and for some reason, I think it dries very quickly and speeds up all the undercoats drying as well.  It acts as a tough top coat, lasting for ages.

If you've got Rainbow, you can easily recreate the Gossip Girl Nails Inc polishes look using cheaper nail polishes - you definitely don't need to spend £20 to get this look!

Other than these sets, has anyone found a good dupe for Rainbow?  I'd be really interested to find out!

Thanks for reading! xx
