This is an easy one. I love cream eye shadows in stick format (Laura Mercier, Chanel, and Bobbi Brown) and use them all the time. They're easy to apply, have an excellent color payoff, and are perfect for travel and use on the go, not requiring any tools or even much of a skill-- just swipe, smudge with your finger and go. By Terry offers twelve colors of Ombre Blackstar Melting eye Shadow (they've been on the market for quite a while, but as far as I know there aren't any limited edition seasonal shades); I picked #5 Misty Rock, a high shimmer taupe that goes with just about anything.
Like other similar products, By Terry Ombre Blackstar is wonderfully creamy and easy to work with. The eye shadow applies evenly as a thin and light layer that you can intensify if needed. I find that By Terry's version, at least in this color, is more sparkly than Laura Mercier Caviar Sticks. Not that there's anything wrong with it. I use Misty Rock on its own or with a touch of teal, navy, or forest green liner. This By Terry eye shadow stays in place nicely till late at night, though I do find that it becomes more sheer as the hours go by.
Bottom Line: very pretty, but I think I prefer Caviar Sticks for their more saturated color.
By Terry Misty Rock Ombre Blackstar Melting Eye Shadow ($43) is available from Barneys, Space NK, Osswald, and Beauty.com.
