As I am not in the same place as the product. I can't comment on product features and know nothing about it (I'm not in the same place as the product or just a seller) for weight and/or mannequin. Also, since the products used by everyone with the same height and weight vary in size. We do not give approval (mislead) answers about product above custom vs. I don't want to give you any false information. For thorough information, you should research the product information and look at it. Sorry not directly answering your questions but I'd say even if you didn't, what would be my advice. You can find your size by looking at the sizes on the inner labels of the products you currently use. If there is a model in the image, when you buy the product in the right size, you can adapt the measurement to yourself. On another note, your sizes may not fit due to ready-made clothing patterns, you can't tell until you try. But it doesn't mean you don't have a size even go big or small it will stay on other sizes. If your real question is what my size and you care for the first time, there are Turkish height and weight tables as I mentioned above, then search online for your size. When you know your size well, the other thing is, as we mentioned above, you can know how the model's posture will look like the right size on you and the product description. The model's body size is given to you to give this information. If you know, you can shop without needing the model's measurements. Thank you for your understanding
