The Drugstore Dupe for a High End Product

I have owned the Dior Addict Extreme Lipstick in the shade Lucky for a couple of years now, and each Spring it comes back out my stored away collection. The formula of this range is quite opaque and gives a nice subtle shine to the lips. Yes, it comes in beautiful packaging, but for those on a budget (like me now), it isn't something I expect to find myself purchasing in all the shades! 
On a recent shopping trip, I found myself in the Topshop on Fifth Avenue (which is amazing FYI - but so overpriced in comparison to the price points in the UK). Having said that, I walked over to the ever improving Topshop makeup stand and my eye caught site of this gorgeous sheer Lip Polish in the shade Nuclear. 
Like the Dior lipstick, the formula is opaque, but buildable and leaves a beautiful soft pink colour to the lips. The only difference I can find between the two, is that the Dior Addict Extreme leaves a stain to the lips as it wears off, the Topshop lipstick does not. But for a $20 price difference, I think you can overlook the stain.
