yes! my first mac purchase, the MA matched me up to NW15, I happily wore it for a MONTH until I was in my boyfriend's car and pulled down the visor mirror to discover that I was an oompa loompa. The lighting in my house is bad, so I really hadn't noticed, plus it was my first foundation ever, so I had no clue what I was doing anyway. I went back and got re-matched to NC15.
definitely. i got matched for nw43 when i was obviously warm and not cool. i looked horrible, my skin looked blah and lacked that glow that it normally has.

Well i didn't actually get missmatched, but i was wearing fake tan (this was also my very first time in mac) and the MA matched me to NC40, but i'm actually NC20/25 lol. Anyways the tan soon faded and now i'm left with a foundation i can't use (tht was smart of me..)
