It is generally acceptable to wear shorts in Turkey, especially in tourist areas and in the warmer months. However, it is essential to be mindful of local customs and dress modestly, especially when visiting religious sites or interacting with locals. 

Generally, it is a good idea to cover your shoulders and avoid clothing that is too tight or revealing, especially if you are visiting more conservative or rural areas.

It is also worth noting that the weather in Turkey can vary greatly depending on the region and the time of year. In the summer, it can be sweltering and humid, especially in coastal areas, and shorts can be a practical and comfortable choice of clothing. 

However, wearing warmer and more modest dresses in the cooler months or higher elevations may be necessary.

It is always a good idea to be mindful of local customs and to dress appropriately when travelling to a new place. This will help you show respect for the culture and traditions of the local people and will help you feel more comfortable and welcome during your visit.
