This is the only polish I've purchased so far from the holiday 2014 collection. When I saw it I knew I had to have it! The Man With The Golden Gun from the James Bond collection is my favorite polish of all time (yes strong statement I know!). Both polishes are very similar except TMWTGG is a flake top only. Don't Speak is slightly different as it has a gold shimmer to it along with smaller gold flakes. Don't Speak slightly changes the color of the polish due to its shimmer so it would probably look best over darker colors.
In the photo below I layered just one coat over OPI I Sing In Color.
I'm not sure when this will be available in stores. I purchased mine on eBay for $24.50. If you missed out on TMWTGG I would highly recommend picking this up ASAP. I'm sure this will be limited edition and sold out quickly. I hope you all have a great weekend!
