I was actually tempted to try the pantyhose route, but they allow a little more water to get in. If you go with a suit with a slick lining (like Henderson Gold Core, Harvey cobalt, etc) they go on FAR easier, and the slick interior forms a seal against your skin. You want to wear as little clothing as possible, so that your skin forms a seal over as much area as possible. My sister in law has the Hendeson Gold Core 7mm farmer Jane, and when we're done diving, her shorts are often still partially dry. My new suit is from aquaflite.com, and with the slick lining it goes on far easier than my old nylon/plush lined 7mil suit, and I stay much warmer due to less water exchange. The aquaflite was a lot cheaper (around $200 cheaper than the Henderson), and if you wanted custom rather than off the rack size, I believe it was only $75 more. My wife (non diver unfortunately) wears smaller sized tops then bottoms in regular clothes, so she would have a similiar problem. If your body is very close to an off the rack size, the additional $75 is well worth it, and still much cheaper than some of the bigger name brands. Hope this helps.
