Courting Lilac is a glaze finish, meaning it shows up lighter than what it looks like from the tube. It contains a bit of a golden sheen and it quite lovely. I know there are similar colors that MAC has come out with, but I don't any of them to compare.
Cut a Caper looks similar to Jazzed and Ever Hip in the tube and on my lips it does look similar, which is a little irritating to be honest. It seems to be a bit pinker on my lips compared to the other two, but it's only slight. This is a lustre finish that leaves a nice glossy peach all over lips. Temptalia has said it reminds her of Strange Potion lipglass, and the coral color of this lipstick does remind me of the lipglass as well. I think it would be a great pairing.
The Faerie Glen is also a lustre finish lipstick that is a very neutral muted color. It's not too nude and has a peachy undertone. It's great for everyday wear.
My favorite is probably Courting Lilac, that golden sheen gives just that extra bit of dimension. It's also great for the fall/winter. Overall the Tartan collection is great for anyone who's looking to purchase a gift for a makeup junkie that wants variety. Since there are so many sets you will be able to find something to suit and match you or the person you are buying for. Beware though, I have heard that some of the eyeshadows are chalky and not as pigmented as usual, so test them before you spend them money. It'll make you and your wallet happier!
