Fashionable to the max

Usage examples of poshest.

I could apologize or make excuses or nothing the lady had thrown her arms around me and kissed me and started thanking everyone from God to the Madonna to half a dozen local saints, although it was me and me alone what removed the ghosts, and then she paid me my million lira and kissed me again, and ran off to tell her neighbors the good news while I moseyed over to the Via Veneto and rented a suite at the Excelsior, which was the poshest hotel in Rome back in them days.
