Dupes for Mac's Cassette e/s from the Heatherette Trio 2??

[Sophia84]

I'm desperate!! I missed the Heatherette Collection last year , I thought I didin't like anything ( silly me!!!) but after I saw the deep purple e/s, Cassette, from the Heatherette Trio 2 but it was too late!! Since then I can't stop lemming it, and I need your help, are there any dupes????

I have Cassette as well and I truly LOVE this colour - and I dont do a lot of purples. If I had to try and dupe it I would use Deep Purple pigment, buts its a little darker and a little more blacker than Cassette - I used them both today!
But like I said I dont own a lot of purples so there may be an e/s closer to this colour, one of the other specktrettes might have a better dupe
