What clothes should I pack for Istanbul in late summer and early autumn?

For mosques and religious sights, pack clothing that covers shoulders and knees; women should bring a scarf to cover their hair. In cooler weather, jeans and a jacket work well; in heat, choose a modest dress without a deep neckline and carry a scarf or pareo.

Regular light clothing works for a daytime Bosphorus outing, but bring a windbreaker for an evening or night cruise because it can feel cool and windy by the water.

For early October in Istanbul and especially Cappadocia, do not pack only summer items: bring jeans, closed shoes and one warm outer layer for cooler mornings and evenings.

In late August, jeans are useful in Istanbul alongside shorts: daytime is comfortable, while conditions can turn breezier toward September. If needed, Wednesday’s Fatih market has outlet jeans for roughly TRY 150–300.
