Abstract: We obtain a classification of double flag varieties of complexity $0$ and $1$ and consider an application to the problem of decomposing tensor products of irreducible representations of semisimple Lie groups.

Keywords: semisimple Lie groups, double flag varieties, complexity, linear representations.
