The panties and swimming trunks fit perfectly, and the size is just right. When swimming, physical activity is flexible.
Great quality but sizing is tight. I am 6 ft 1 and 175 lbs and would wear a Medium / 32 inch waist in North America. Should have ordered 3-4XL. XXL is too small. XXL = Small in North America, would be fitted for someone with a 30 inches waist.
