no but it is good to wear one
I would suggest NOT wearing your swimsuit on under your wetsuit. It will bunch up and leave you in a world of discomfort. Instead wear a spandex like short under your wetsuit - i prefer Helo shorts (it's a brand). Then wear your boardshorts on OVER your actual suit. At least that's how we do it when Kiteboarding in MI.
People wear a watch, wedding ring, wristband and a wig. People wear a wetsuit and walking shoes.
Kids can wear just about anything on Halloween.... fursuits? Why not?
No they are not harmfull at all [as long as you wear a chain mail wetsuit anyway.]
Yes. The thickness of the wetsuit most certainly factors into your buoyancy. Less neoprene equates to less lead. Cold water divers learn this quickly when vacationing south.
The way wetsuits fit is very important. Typically if you are a Women you will want to wear a Womens wetsuit. The overall tightness of the Wetsuit can play a major roll on whether or not you stay warm in the water. See related links for an example of women's wetsuits.
Because the water is more cold than regular water when u swim with them.
The bikini/bathing suit bottoms will come off if they dont.
A bathing suit for starters, a rash guard, or most surfers wear nothing under. A common additional item to wear under a wetsuit is a one piece lycra suit. The benefits of this are that it makes the wetsuit easier to put on and off, and the lycra doesn't compress. For instance someone diving a 5mm farmer john (2 piece) wetsuit and a 2mm lycra dives deep enough that the wetsuit has compressed to half its original thickness. This diver now has 2.5mm of wetsuit covering their legs and arms, 5mm covering their core (chest, stomach.) Now when you add the 2mm from the lycra which hasn't compressed there is actually 4.5mm on the legs/arm and 7mm over the core area. A diver in a 7mm farmer john at the same depth is left with 3.5mm on the legs/arms and 7mm over the core. If you double the depth at this point the 5mm and the lycra gain a lead over the thicker wetsuit. The free aditional benefit to this item is that you may be able to get rid of some extra weight as you can use a thinner wetsuit which will require less weight to get you under.
It is not safe to wear halloween makeup for a long time because most halloween makeup is thick and toxic and overtime irrates the skin.
