Not sure if you are talking foundation or fake tan, because you mentioned leg foundation and the only product I've seen in relation to legs for this particular brand, is fake tan. If it is fake tan you are talking about, then I've seen the face one for this on the Sally Hansen stand in Dunnes Stores shops. Hope that helps.
This may or maynot be the one you refer to - on the 'Off the rails' website (rte) it says that the airbrush foundation was Dior €44 from Brown Thomas- has anyone else tried it? - i would love to give it a go but would love a second opinion
