The fabric is from Tessuti. The very cute ric-rac elastic was from elingeria, which has sadly closed.
After reading other reviews of the pattern, I went down a size, but I wish I hadn't as the suit is very snug and I had to remove the waistline elastic. I added maybe 4 cm of length. I sewed the back straps in a slightly different position as I was worried about side gaping. I had to add darts to the upper front, near where the triangle cut out bits are. Next time I will modify the pattern so that I don't need these darts.
