you might also try it backwards. go to Palais des Congres (Porte Maillot) Hall and look for events. i get invited to all of them, but since i do not read french, i do not go.
Palais des Congres (Porte Maillot) Hall. is a surprisingly small place when compared to the trade show places in germany, italy and GB.
they charged us for tickets, but we went anyway as an excuse to take a business trip to Paris. when i stopped going, they mailed us comp tickets.
was not for the chanell hermes etc sales. we bought those bootleg in italy anyhow.
