I had my face made up in Mac on Kings Road last week and ended up buying quite a few things. When I put the foundation on the next day, I realised they have given me the wrong shade - am completely orange. I don't think they made me up in that shade as I looked fine in the shop. Anyway, as luck would have it I'm passing that way tomorrow so take it back, but will they send me packing? I have the receipt but obviously have opened the bottle....
