The measurement of strangeness production is one of the powerful tools to study the thermal properties of the QGP and while strangeness enhancement is a well established experimental observation in heavy ion collisions, its interpretation is still debated.

In particular the study of (multi-)strangeness particle production as a function of the event multiplicity in different collision systems, reported by ALICE, has shown a smooth increase of strange particles relative to the non-strange ones with event multiplicity.

We here present the latest results on multiplicity-dependent strangeness production in all the available colliding systems at the top LHC energy. Furthermore, recent measurements of mesonic and baryonic resonances will be presented to discuss the system size dependence, to investigate how hadronic scattering processes affect measured resonance yields, as well as the interplay between canonical suppression and strangeness enhancement.
The experimental results obtained in pp, p-Pb and Pb-Pb collisions will also be compared with the theoretical predictions.
