Obviously Sephora! They have so many polishes that we can't get over here- I increased my nail polish collection by approximately a polish a day of our 10 day NY holiday! I also ordered some bliss kiss nail oils to be sent to our hotel, as my mum and I had wanted to try them out so it saved on the wait time for delivery to the uk. Enjoy it, I can't really call my experience a holiday as once I got over my bad jet lag every day was jam packed full with plans as it was a once in a lifetime trip; we only could afford it as I won the flights!!
