MAC Peachstock Lipstick is a warm, creamy, opaque peachy-beige with a satin finish. I'm actually not a big fan of MAC Satin formula lipsticks, but Peachstock actually looks great on it's own. I have to say that this is probably one of the most flattering nudes I own for my skin tone (MAC NC40). I highly recommend this shade if you're olive skinned and its hard for you to find the correct nude that won't wash you out or give you the appearance of concealer lips.
MAC Peachstock is a MAC Pro lipstick and can be purchased at your local MAC Pro store.
MAC Everhip Lipstick is a vibrant, coral-pink with a semi-shiny finish. It's the MAC Cremesheen formula, which I love, but for some reason Everhip doesn't seem to glide across my lips as easy as my other Cremesheens. It's creamy nevertheless, but it's pretty sheer, and I find myself swiping it several times before I'm satisfied with the opacity.
MAC Everhip is a limited edition shade, and will only be around until supplies last.
