Evidence

Only the headgear remained un-Westernized, and for good reason. After the Kemalist Revolution in Turkey, even this last bastion of Islamic conservatism fell. The Turkish army, along with the general population, adopted European hats and caps, and before long they were followed by the armies, and eventually even many civilians in almost all other Muslim states. — Bernard Lewis, From Babel to Dragomans, 1144
