The Posing Suit has a daring 1/2" (13mm) side, a slim-cut European seat to show off your glutes, and a partial contoured front pouch that gives the suit a smooth front with a contoured shape. The 1/2" (13mm) side seam can be a bit cumbersome to sew, making this pattern more difficult for the beginner. It is designed to be made without a lining (see sewing tips about swimwear lining). The pattern is made for waist sizes SMALL 28-30 inches (70-75 cm); MEDIUM 31-33 inches (77.5-82.5 cm); LARGE 34-36 inches (85-90 cm). Requires: 1-1/2 yards (1.37 m) spandex; 1-1/2 yards (1.37m) of 3/8 inch (9mm) elastic; 1-1/2 yards (1.37m) of 1/4 inch (6mm) elastic. Please see this note regarding fabric requirements. Level: Moderate
