A facile and robust method is developed to engineer the shape of non-crosslinked poly(styrene) (Nx-PS) particles. Our strategy allows for the formation of and controlled switching between spherical and three anisotropic morphologies: convex-convex, plano-convex and concavo-convex. The different morphologies are accessible from spherical Nx-PS by modifying the annealing time at elevated temperatures and/or concentrations of surfactant. Furthermore, shape transformations between different morphologies are also achieved. The strategy of engineering the shape of particles might be applied to other polymeric colloids holding great potential in achieving <i>in situ</i> colloidal crystal phase transition.
