I really love Milani, but there are so few places that sell it where I'm at, that I can barely find it, because the places that do sell it are always sold out.
Out of the ones that I do have I love
Shock - although it is more sheer than Stars N Rockets, I love them both. On me there is a subtle difference and I personally wear Stars N Rockets more, but I will always love Shock.
Taffy - a very light pink. I don't have any light pink MAC shadows yet, mostly because I always end up buying dark or bright colors! But Taffy is a nice sheer, light bubblegum pink.
Moonlight - very very very pretty reflective white. On me, it seems to look blue sometimes, but it reflects other colors that are around it. Lovely color. I would totally recommended this to anyone.
Garden Mist - not sure if this has a dupe in MAC, but I love it regardless. It's a nice light grassy green. More lime than true green. It does take a lot of it to show up on me, but maybe thats cause my skin is slightly...green? Or it's just sheer.
Skyline - its a light sheer true baby blue. shimmery. lovely over moonlight. not sure if it has MAC dupe. Maybe Moon's Reflection? I've never seen MR e/s on...so I have no idea. Just a guess. But I do love skyline! Its pretty and more pigmented than Garden Mist but less so than Atlantis.
and finally my favourite! Atlantis!!!! It's a shockingly bright, amazingly pigmented, smooth matte blue. I suppose it might be duped by Electric Eel. I don't have EE e/s but my guess, is that it might be closer to Clarity e/s because Atlantis is a matte color, and although probably darker than Clarity, Electric Eel is a satin with shimmer.
I actually have swatches of these on my arm right now, but after I did the swatches, I realized that my camera is in pieces. It broke yesterday after I took pics of my latest haul. Soooo sad.
But I hope this helped anyway and if my cam gets fixed I will post pics of the colors I have.
