I wear a Bare XXXL 2 piece (farmer john + jacket) 7mm wetsuit (the water is typically 54 Deg F in the summer). I have a very hard time getting the farmer johns on. Once I'm at the dive site, I need to start donning early just so i can finish late - if I take too long, I'll get left behind.
The suit fits well (much better than the XXL), once it's on. The problem is getting it on my legs and feet. I have to really work hard to pull it on, then once it's on, I have to be concerned with overheating due to the herculean efforts to get it on.
I think I'll try the pantyhose trick on my dive tomorrow morning. I'm pretty secure in myself, so that's not a problem. Since most of the people I dive with dive dry (and wear precious little under their drysuit underwear, it won't look funny for me to do the ol' change at the car door thing. I just have to figure out the best size. And if someone decides to video tape me, then I'll have to worry about what color looks best with my trunks.
If it works, I'll have to figure a way to explain it to my wife...
