How to choose my size?

Thank you for providing the additional information. Based on the information you've provided, here are a few tips for choosing your size:

• Using your height and weight is a good starting point, but it's not always the most accurate way to determine your size. Different body types may require different sizes, even if they have the same height and weight.

• If you're unsure about your size, it's a good idea to choose the size you normally wear comfortably. This can give you a good baseline for determining your size in a particular brand or style.

• European sizes can be different from sizes in other regions, so be sure to check the size chart for the specific brand you're interested in. Remember that the size chart is for reference purposes only, so it's important to try on the item to ensure the best fit.

• Model size references can also be helpful in determining your size. In this case, the model is 180cm tall and weighs 84kg, with a chest size of 106cm. The model is wearing a size L replica or size XL authentic. This can give you a good idea of how the item may fit, but keep in mind that everyone's body is different, so the fit may not be the same for you.
