The short version
Dress much as you would in southern Europe, with a scarf and covered shoulders and knees available for mosques, and proper shoes for ground that has been walked on for two thousand years.
For mosques
Hagia Sophia, the Sultan Ahmed Mosque and the Süleymaniye are working places of worship, not only monuments. Women should carry a scarf for the hair and wear something that covers shoulders and knees; men should avoid shorts. Shoes come off at the door, so slip-ons save you crouching in a queue, and socks without holes are a genuine kindness to yourself.
Many mosques lend a covering at the entrance, so arriving without one is not a disaster. Having your own is simply easier.
Shoes
The single most important item. Ephesus is marble worn smooth and slippery by millions of feet, with a slope from the upper gate to the lower. Cappadocia is dust, loose volcanic rock and steps cut into cave floors. Istanbul is cobbles and hills. Closed shoes with real grip, already broken in.
Layers for the plateau
If Cappadocia is on the itinerary, bring a proper warm layer whatever the month. The plateau is high, the nights are cold even after hot days, and a dawn balloon flight is colder still. People pack for the Aegean, go inland, and spend the trip buying fleeces.
Sun
Hat, sunglasses, sunscreen. The archaeological sites have almost no shade, which is a fact about the sites rather than about the season, and it applies at Ephesus and in the open Cappadocian valleys from May onward.
Practical small things
A refillable water bottle. A power bank. A small daypack that will hold a shed layer, because you will be taking one off by eleven and putting it back on at six. A universal adapter.
What you do not need
Anything formal, unless you are going somewhere specific. Turkey is relaxed about dress outside religious sites, and the coast is as casual as any Mediterranean country.
