Unlike other examples of fermion pair production in e{sup +}e{sup -} collisions, we show that top-quark pairs are produced in an essentially unique spin configuration in polarized e{sup +}e{sup -} colliders at all energies. Since the directions of the electroweak decay products of polarized top-quarks are strongly correlated to the top-quark spin axis, this unique spin configuration leads to a distinctive topology for top-quark pair events which can be used to constrain anomalous couplings to the top-quark. A significant interference effect between the longitudinal and transverse W-bosons in the decay of polarized top-quarks is also discussed.
