Combining heavy quark effective theory and the chiral Lagrangian approach we investigate radiative decays of pseudoscalar $D$ mesons. We first reanalyse $D^{*} \rightarrow D \gamma$ decays within the effective Lagrangian approach using heavy quark spin symmetry, chiral symmetry Lagrangian, but including also the light vector mesons. We then investigate $D \rightarrow V \gamma$ decays and calculate the $D^0 \rightarrow \bar{K}^{*0} \gamma$ and $D^{s+} \rightarrow \rho^+ \gamma$ partial widths and branching ratios.
