I am looking at buying a full leg Fastskin for nationals, can someone help me with the sizing? I wear a 36 in a practice suit, but the Fastskin sizes don't seem to go higher than 30. I am not a huge person, pretty average for a masters swimmer, but there is no way I would fit into a size 30 lycra Speedo. Are the technical suits on some other size chart? Or do I need to keep looking for a size 36?
