hi! I just got my new neoprene but I can't draft my pattern yet because I'm not sure if I should use measurements taken with my monofin on or with it off. I ask this because last time I used measurements with mono on and since I'm slightly bow legged I then had a giant gap between my calves and when I got the tail wet the gap would fill with a lot of water and drag me down and would also sink in and I've noticed no one else's tails have this gap.
