MAC Giddy is a slightly cool-toned, medium pink with a pearl finish. It is a permanent lipstick that retails for $20.00 and contains 0.1 oz.
MAC Giddy Lipstick ($16.00 for 0.10 oz.) is a muted, medium pink with warm, rosy undertones and a soft, gold shimmer. Officially, it has a Lustre finish, but the texture wasn't quite as glossy--a little drier overall--and the pigmentation was mostly opaque, which is unlike traditional Lustres, as those tend to be sheerer. It lasted for three hours on me, but it was somewhat drying. YSL Corail Jalouse (32) (P, $34.00) is less shimmery. Tarte Pink Peony (P, $16.00) is darker. NYX Chic (P, $4.00) is a touch lighter.
