Adult Natural Rubber Wetsuit in Long Sleeve Women’s Spring Suit, size medium 2.0 mm Japanese Neoprene (soft, stretchy natural rubber) made from reputable Yamamoto company Only worn to surf one time. I love this company and wear their other swimsuits often! I sized up because I had so much trouble with size small springsuits riding up, but this suit is too big for me. I ordered the same suit (I love it that much) in their smaller size. I would suggest this suit for individuals who range from size 6-8, but see the specific sizing details below. It is so flexible and stretchy, making it super comfortable in the water. Body length: 14.6 inches Chest width: 15.4 inches Waist: 15 inches Hip width: 15.4 inches Sleeve length: 25.2 inches Sleeve opening: 3.5 inches Thigh opening: 9.1 inches Side seam 14.6 inches
