Make sure you bring in your empty Mac containers cause they will take 6 and give you a free lipstick! For sure go see a consultant. They are picky about who they hire and they are sure that they know how to to push themselves. Mac has every color under the sun and I'm sure you'll be able to mix a combo to get the color you want to achieve.
If you want a peachy tone lipstick i strongly recommend the MAC cremesheen shy girl lipstick colour and if you want a little bit extra pair it up with the MAC creme sheen glass calypso lip gloss to apply over top for extra shine. :)
