I don't think your leg was being pulled, but I'm pretty sure there are no actual laws on these issues. :-)
If you have a wedge heel, bring those instead of spikes. Easier to get through the sand. And bring your cheap pair, shoes get ruined pretty easily.
If you want to put a t-shirt on to guard against a sunburn, probably a good idea. I have heard from many sources that all the sunscreen we put on is damaging the marine environment. I also *think* I heard that it can help if you apply the sunscreen an hour before you get in the water. You're supposed to put it on 1/2 before being in the sun anyway, so it can't hurt.
