Its EXACTLY the same as The Sex Kitten. The only reason I wouldn't buy (or actually swap for it) again is because now I have two of the same palette.
I have begun collecting the QC, and most of my purchases have come from ebay. Much to my surprise, when The Glamour Girl arrived it appears to be the exact same pallette as "The Sex Kitten". Since I love the sex kitten, and I use my QC, this is a plus, but some may not see it that way.
