A dupe for Illamasquas blush in Sin?

It's safe to say I'm a bit of a blush addict, so I try not to get dupes, we don't want anything going unloved now :) My Illamasqua Sin was a present from a friend of mine that I received a good while ago, after I took a good look, I saw a big resemblance to my Topshop cream to powder blush in crushed berry. After some comparing here's what I found.

Its clear to see that the topshop blush has far more of a pink to it, whilst the Illamasqua blush is more purple. This is a big contrast to how they look in the pan as they look near identical. Now you can see that once blended out, the differences become less apparent, however they are still noticeable.

Verdict? I'd say crushed berry was quite close to sin but not an exact dupe, which is great for me as now I know I don't have multiples of one colour. Crushed berry is the purse friendly option because topshop blushes retail at £6.00, and Illamasquas offerings are on the high end side retailing at £16.50. Both colours are great but I do love sin a bit more, from the above swatch its clear to see how pigmented it is, which helps it to last a good few hours on my face.
However both are great to have in your collection.
