Hello, First of all, thank you for your interest. Given that your height is 150 cm and your weight is 53 kg, our product usually fits you in sizes S or M. However, since the pattern of our "Black Backless Crop Women's Blouse MG1851" model is crop, I recommend that you take the size chart into consideration in order to fit your body structure perfectly. You can check the size chart on our product page and compare your chest, waist, and height measurements. If you want a more comfortable use, you can choose size M, and for a more fitted look, you can choose size S. I would be happy to help you find the best fit for you. I would wait again if you have any other questions. I wish you good shopping. Best regards, Deniz Madmext Team
