If you're diving in a wetsuit wear a bikini or tankini under it, a one piece can be a big pain.
When do you take the stuff off:
Between dives you can peel down the top half of the suit and put on as many layers of clothing as you need to stay warm. I prefer a polar fleece top and something to block the wind, a duster length coat works well. They do make scuba specific long coats to wear over your wetsuit between dives. A warm hat and mittens are also nice to have when you get out of that cold water.
At the end of the day pull off your wetsuit and change out of your bathing suit wherever you feel comfortable doing so. If you pay attention at a dive site you can be stark naked for a short period when no one is looking. I often quickly change out of my suit top and into a shirt with a whole herd of divers nearby and they never notice. (Tech divers are my favorite, they are so engrossed with their gear that you can walk around stark naked for 20 minutes and they'll never notice
)I then put a skirt on over the bottoms before removing them and slipping into panties. Yoga pants and bouldering pants are great for diving, easy on/off and some are pretty warm too.
The best investment I made for my shore diving was an indoor/outdoor rug/doormat. It's nice to have something to stand on in your bare feet while changing, just don't stomp all over it with your muddy/sandy booties. I've also used a carpet remnant/carpet car floormat but it absorbs water and if you don't let them hang to dry completely they get gross. Bring an extra one for your buddy otherwise they might take over yours
Sure beats trying to stand on a picnic table to get dressed.
Hair is another issue, if you have medium or long hair get a spray-in conditioner for the post-dive day brushing. Hair does funky things under hoods and the conditioner makes fast work of dive knots.
If you do dive wet get a hooded vest instead of a regular hood, you'll be warmer. Three-fingered gloves are nice too, you lose some dexterity but if your hands are freezing in five-finger gloves you don't have any dexterity anyway. You would be surprised how much nicer cold water diving is when your hands are warm.
Hope this helps!
