With a height of 164 cm, 86 cm chest, and weighing between 45 kg and 50 kg, I usually wear a Chinese/EU size S/M. However, based on reviews, I ordered size L, which fits comfortably and looks exactly as shown in the product images. The synthetic material is stretchy. The bottom hem tends to roll up, possibly due to the size or the design. While the straps are comfortable, they appear delicate, so machine washing is not recommended. I would consider purchasing another one, but not at the original price of 28€. Delivery took two weeks. I did not contact the seller. I am satisfied with the purchase.
