I got this from my local drugstore for a couple dollars. This caught my eye because it reminded me a lot like OPI's Last Friday Night from the Katy Perry Collection. This to me is a perfect dupe, I didn't have a chance to get the Katy Perry nail polish but I have seen lots of swatches! I used about 4 coats thi is gorgeous! OPI compared to Confetti I see no difference except the price and the brand! It is a bit bluer though.
