I bought every color available in these duos, and was impressed with the looks each one created! I use matte shades from another palette or singles, in my crease, then use these duos on my lid. I always use an eyeshadow primer set with powder too. And these look stunning on my eyes, even many hours after application!
I bought #5 and the colors are beautiful. The formula is smooth and relatively easily applied. The only issue that I have with this eye shadow is that the purple color has larger pieces of silver glitter interspersed throughout. The glitter isn't concentrated in the eye shadow though, it's just a little speck of glitter every so often.
I ordered number five (crazy pLum) and number seven (neutral beige). There was definitely a difference in the colors. I absolutely love crazy plum! Both shades have a perfect shimmer and looked great on my olive skin. The neutral beige was much more brown than I intended to get.
I purchased all of these eyeshadows. They look different in the picture, however when you receive them they all look almost the same. If you only buy one color you will be okay. Don't get more than one or you will be very disappointed.
