Dear customer, Thank you for your interest. Our product is in a regular fit mold, so it may be appropriate to prefer the size you use in daily life; however, we should not give a clear guidance on the size. Since the height, weight and body information of the model is not shared by the manufacturer, we cannot provide you with exact information on this subject. Therefore, when choosing your size: - We kindly ask you to review the Trendyol size chart - Size comments and photo evaluations under the product - If available, the sizes of similar dresses you have bought before. Since you mentioned that the top part is a bit bulky, it would be helpful to check the reviews in the customer comments regarding the "chest/shoulder area."
