I have both 88 palettes.. I ordered the regular one (I hate to call it matte cos they're not all matte) a few months ago and have been using it sporadically - it's ok, but it's not something I went to all the time. Then I ordered the shimmer palette cos it was on special, and I LOVE it. I've been using it every single day - when they say shimmer, they're not kidding
I love the colors, especially the blues, there are so many gorgeous carribbean-hued blues, from light to dark, and they look amazing on my blue-gray eyes. The greens are gorgeous as well. I also like the silvers and browns, there's a great taupey color there that's so beautiful for a toned down look. I haven't experimented much with the pinks yet. Personally I don't find the shimmer palette to be chalky, and as long as I use UDPP the colors stay on fine. A lot of times ppl come in and ask which palette they should get if they just want one - I would definitely say the shimmer palette - I'm really happy with it
Next I want to get the neutral palette and the contour and blush palette, but that'll have to wait a bit, as I've been doing entirely too much net shopping.
