And it's thousands of year old cultural symbols, the traditional Sindhi Cap and Ajrak cloth.

The comments which were made on November 21, 2009 in the current affairs show Meray Mutabiq by Shahid Masood. The anchor's condemnation caused a wave of fury through out the province with the local language media calling for protests and apology.
Then the sindhi media channel KTN gave a formal call for the day to be observed on first Sunday of December. The call was subsequently endorsed by all the parties of Sindh except the Pakistan Muslim League.
The day began with rallies and walks in all the district head quarters of the province. Residents throughout the province donned the caps and danced to the folk songs, reaffirming their resolve to protect the Sindh motherland from conspirators.
The call mobilized the people who started purchasing of Sindhi caps all over Sindh. Such enthusiasm from the masses resulted in historic sale of Sindhi Topi with people purchasing it on high prices and sharing it with each other after the stocks ran out.
