  I present a simple self-consistent dust spectral energy distribution (SED)
model that has been applied to fit the well-sampled observed UV-to-radio SED of
four nearby starbursting dwarf galaxies. The main originality of this model is
that numerous multi-wavelength observations, from UV to millimeter (mm),
constrain in a self-consistent manner, both the local radiation field and the
grain size distribution. I finally present the results of our model and discuss
the average dust properties in these dwarf galaxies.
