i was curious if i wear a wetsuit when going scuba-diving should i wear a swimsuit or just my clothes just curious,,,

Wear rash guard tops and bottoms ... Google ...

Backcountry.com, Altrec.com and REI.com are good sources ... Have FUN!

You should be able to answer this yourself ... a wetsuit is the opposite
of a drysuit. A drysuit is impervious to water. A wetsuit allows water to
permeate the suit, thus a thin layer of water is "trapped" between your
body and the suit, whereby your body "heats" that thin layer of water.

It is recommended that you wear a swimsuit - you'd most likely be too
uncomfortable wearing street clothes under a wetsuit, plus those clothes
would become soaked, immediately, so you'd have to have a 2nd set.

sorry i am just new with this and not sure what to do, so when you wear a wetsuit you still get wet or your dry

You get wet, the lil layer of water is trapped between you and the suit, and warmed by YOUR body heat, thus insulating ... See?

As I just explained it ... that's why it's called a *WETSUIT*.
Please re-read my reply.

I prefer shopping for all this stuff at a surfshop (or sailboard shop),
but yes, a rash guard is a good idea, especially if you're "renting" a
wetsuit (ick!). FWIW, I've been surfing for about 35 years (and I owned
a surfboard & sailboard manufacturing company for about 5 years).

The best reason to shop at a local surfshop is the level of customer
service, proper fitting and customization, and best of all, you're
supporting a local retailer, instead of some overbearing corporation.

what is a rash guard if you don't mind answering

... A soft, clingy shirt and shorts that prevents sunburn and rashes ...

A staple for water sports!

Now, get Googlin' ... just plug 'rash guard' into the 3 sites I provided!

If you have an REI, go try 'em on there, or wherever you are gettin' this wet suit!

YOU need to do your research, hon, we've answered ... Have fun!

It's a thin tight-fitting garment (spandex-like) that you
wear, which is designed to keep the wetsuit from
"rubbing you raw".

A rash guard won't be as important when SCUBA diving
as it would be for surfing or sailboarding, since you're
not "flexing" near as much. Lots of surfers wear rash
guards even when a wetsuit isn't required, to keep from
getting "rubbed raw" from the wax on a surfboard.

Wetsuits have very well-defined seams and have a
tendency to rub against the skin (the whole suit does,
actually) and can cause a "rash" of sorts. But as I said,
it's not as important to use a rash guard when SCUBA
diving ... if you have access to the wetsuit you'll be
wearing, I suggest putting it on and swimming around
in a pool (or at the beach) to see how it "works"

My female friends usually wear one piece bathing suits under their wetsuits. Sometimes they just wear underwear if their bathing suits have started to stink.

Your question is a little odd since you should not scuba without taking a proper course and part of the course explains the changes in buoyancy caused by the suit and the technique of peeing in the suit if you get cold. The pee warms the layer of water between your skin and the wetsuit (don't do this in the pool!).

During your class, try on both 1/8, 1/4, and 3/8 inch thick suits in both full and shorty designs and practice in the pool with each to get a feel for what you need. If you are cold natured you will need a thicker suit. I am very warm natured and seldom wear one at all... and even then only a thin shorty.

A thick suit will make you massively buoyant and you will float like a cork so you will need a lot of weight to compensate. The thicker suit, especially the full, will restrict your movements also so you want the least thickness in which you can be comfortable. Outside the water you will overheat quickly in a full suit so keep that in mind too.

The best scuba course is PADI and all this type of information will be discussed in great detail.

Be safe and don't rely on some "quicky" weekend course.

my friend is showing me it all since she does teach a swim class for scuba diving, and i did look up the rash guard and that is much like the shorts what you call them when surfing

would a one-piece be better to wear under a wetsuit or does it not matter

My friends usually wear one pieces but I have seen and known many who wore a two piece. The last dive master I saw in Honduras wore a two piece.

Being a guy, I don't really know, but it appears that they just wear what they would normally wear to the beach. The only exception to that is that you don't want to wear anything that has little beads, ruffles, lumps, etc., because it will start to hurt under the wetsuit which is very tight.

I didn't know any of this. lol
