B[e] stars are characterized by a large near and mid infrared excess produced by an envelope of hot circumstellar dust. Based on interferometric observations, I show why modeling with a central source surrounded by a dust shell is not a good approach for these objects. Next I show a "gas + dust" model developed at the "Observatoire de la Cote d'Azur" which reproduces more faithfully both photometric and interferometric observations. Finally, using observations obtained at the Keck I telescope, I show how the modeling allows us to improve our knowledge of the circumstellar envelopes of these peculiar stars.
