I love reading these stories because I just love make-up and MAC is my favorite!
For me, it all started out because I needed make-up for one of my projects. My groupmates and I were going to present our Japanese Studies project as a rock band and I needed a foundation to cover up my terrible acne scars, as well as really out-there make-up colors.
My roommate recommended that I try the MAC Studio Tech Cream foundation which, once applied, made me look like I had porcelain-smooth skin! It was awesome! The MA, a really bright and colorful gent recommended that I try the 2004 fall palette (I think it was a Trend palette or something like that) to complement my goth-rock costume, and it was perfect! Cranberry eyes, crayon red hair and jet black clothes: it made me really stand out in our "band" even though my groupmates had more colorful/creative clothing and hairstyles than I did.
Ever after that, I've bought many palettes, brushes, single pan shadows. It's been a really long time though and my love for MAC hasn't diminished.
