The 6 Beauties Play It Cool Eye Shadow Palette released with the Holiday 2010 Tartan Tale collection. It is my FAVORITE of the 4 palettes. Purples, of course, are awesome, but the upper 3 colors of the palette are so gorgeous, unique (upper middle one!), and awesome to work with.
The 6 colors in this palette are Silverwear (F), Hold My Gaze (F), To The Ball (S), Altered State (VP), Magic Moor (VP), and Heather Belles (S). It also comes with a 213SE but, I'll say it again, PLEASE replace that with a mini 239. Seriously.
Beauties Play It Cool retails for $36 USD plus tax, but is sold out on the MAC Website. If you want to purchase this you could try your local MAC counters or stores, or at other online department stores. It'll probably be hitting your local CCO within the next few months as well, so keep your eyes peeled for it there to score a sweet discount.
