Hello dear customer, thank you for your interest. Our product is in **regular fit** pattern, therefore, you can generally prefer the **size you use in daily life**. However, it is technically not possible for us to give you an exact size based on your height and weight information. Since the manufacturer does not share the model's height, weight, and clothing size information, we cannot provide you with exact information on this subject. In order to choose the most suitable size for you, we kindly ask you to: - Review the **size chart** on the Trendyol page, - Pay special attention to **customer comments about the size**, - Use the sizes of the polo neck t-shirts you are comfortable with in your wardrobe as a basis. This way you can evaluate our product more accurately.
