Don't know if this will help, but- Went on an 2015 April trip and wore a Kokatat Gortex suit with built in booties (a must) part of the time. Worked great and so glad I had it as we flipped in Lava and it was a longish swim. My only complaint was getting out of it when I needed to pee, needing someone to unzip me ( I could zip up ok) and dealing with the wiggle dance getting out of the neck gasket. Of my lady friends, no one has a suit with a relief zipper . . .
Have fun! We're slatted for a July 2019 trip - ooh it'll be hot!
