MAC is a brand. It is a pretty common mall store, but they also are in most department stores.
It shouldn't be hard to find.
This is from a post I found...
I found this in an article where she talked about what makeup she uses:
“In my make up bag, I always have MAC blush in ‘Pink Swoon,’ along with their travel size blush brush. A MAC lip liner in ‘Stripdown,’ with MAC lipstick in ‘Angel.’ And Nars lip gloss in ‘Turkish Delight.’”
Her blush, lip liner, lipstick, and lip gloss are all in the soft pink range. Nothing strong or too bright for her lips.
MAC Blush- Pink Swoon– Clearly Pink (Sheer tone Powder) $17.50
MAC Lip Liner- Stripdown-Naked Nutmeg (Pencil) $12.50
MAC Lipstick- Angel- Soft Pink (Frost) $14.00
Nars Lip Gloss- Turkish Delight- Pink Sorbet- $23.00
As far as the one beauty item she could never live without, that’s the Nars lip gloss in ‘Turkish Delight.’
