Bikini Top & Bottom (WS13)

See pics for sizing and to help further: I'm a 38/40/(sometimes 42), and I don't think the top is for size 14, really - more 12-10? If I lay one of the triangles out flat it's about 18-19cm across the bottom and 15-16 along the other two sides. The bottoms are about 36-37cm across the waistband.
