Went shopping for a tinted moisturiser/BB Cream. At the Bobbi Brown counter the assistant said I could wear either Medium BB Cream or the Fair. She tried a bit of both at my jawline. Because the lighting is so odd in department stores, I said I'd finish my other shopping and come back. An hour or so later, I'm back at BB Counter. The lady who'd matched me was on her break so I said "I'd like to buy the Fair Bb Cream" to another SA with a Bobbi Brown badge. She said "no" I'd don't think that's right for you, I'd say the best shade would be Natural. So, I ended up buying nothing as in the time period of approximately one hour my Perfect Match (according to the experts) changed 3 times. And at £29 a pop, I thought "back to the drawing board".
Why does this happen? I know that over the course of the day, your complexion can change but, 3 times....in an hour.
