Italian fashion chamber urges fashion community to keep up pressure on Missoni search

MILAN - The fashion world is urging authorities to keep searching for the missing CEO of Missoni as Milan Fashion Week gets under way.

The Italian National Fashion Chamber has urged the fashion community to post messages on social networks to keep the search for Vittorio Missoni at the centre of authorities' attention.

And designer Carlo Alberto Corneliani expressed solidarity with the Missoni family before showing his collection, the first of Milan Fashion Week, on Saturday.

Vittorio Missoni went missing with three other Italians and two crew members when their twin-engine aircraft disappeared off Venezuelan resort islands on Jan. 5.

Despite the uncertainty, the Missoni fashion house confirmed its menswear preview show for Sunday. In a message posted on Facebook, designer Angela Missoni expressed gratitude for messages of support.
