Search engines are your friend.   There are likely additional places for each creator.

Warlokk (retired) -- predominately here at Insim and InSimAdult. The Mystical One also did a cumulative posting here.
 http://www.baldninja.com/bodyshape.php.
VanityDeMise (retired) -- may have some things at InSim or InSimAdult. Much of her stuff can be found at Sims Cave (and in Other Creators in my signature line)
Snarf/Lion-O (active) -- much of his older things can be found at Sims Cave.
Gothplague (retired) -- her site and another site (Wooden Simolean) that hosted her works seem to have vanished now. There may still be some on InSim and InSimAdult.
Cenor (retired) -- his site www.sinford-sims2.de is gone. Some of his things can be found in Other Creators in my signature line

Another catch-all for some of those creators' works is also found here.

Teen C and Teen D only describe the tops. You also have to decide on the hip size. Small, Medium, Large or XLarge. So for Teens, it's C-Sm, C-Md, C-Lg and C-XL and Teen D-Md, D_Lg and D-XL. (There's no D-SM). Finding teen meshes with Pregnancy morphs can be challenging since the vanillla game did not have teen pregnancy and the first creations of Warlokk meshes for teens didn't include them either. All of Warlokk's teen meshes did include the fat morphs. VanityDeMise did make a number of meshes with full morphs for Teen C-Lg and Teen D-Lg.

For CPU, Warlokk's early creations only had Fat morphs as well (except for full body nude MESH_afBody_ClassicPinup_Naked which has both). But Warlokk's X-Hi meshes which came out later do have both morphs. Cenor had a huge project he did which converted nearly every Maxis outfit to CPU and added morphs to them. He also developed a CP Teen shape and converted a number of Maxis outfits to it with both morphs. Other creators such as Gothplague, Snarf/Lion-o and JulieJ have all made fully morphed CPU meshes.

(I have a number of recolors/conversions of fully morphed CPU clothing found in my signature line. If the downloads themselves don't contain the mesh used, they can be found in the "Clothing Meshes" download.)

This just applies to clothing. Bodyshaped skintones which show "true-nude" (only in the shower or with a nude mod) are built differently and depending what meshes the creator used when making that skintone may or may not have full morphs. But if you don't have a nude mod and don't care what they look like in the shower, then that's not an issue.

Some of Warlokk's numbered series (because there were so many of them) weren't very popular so you might not find many other clothes for them if you want much variety unless you make/convert them yourself. Popularity on those tended towards larger than Maxis default (which Warlokk classified as 34Bdef-34) both in bust and hip sizes. 

Some of the named sizes did have a lot of interest so people made a lot of clothing and additional meshes for them. Three of those which you can find quite a bit of clothing for are Classic Pinup (CPU) which is larger than Maxis default both in breast and hips, Fashion Model (FM) which is smaller in both breast and hips and Voluptuous Gal (VolGal or VG) which is larger than CPU in both.

Yes, it depends on the shape and the meshes. And depending on what shape(s) you are interested in, other creators have added morphs to some of the Warlokk meshes that didn't have them or created new meshes that do have them.

I use several of Warlokk shapes (some numbered series, CP, FM, etc) and I pretty much only use meshes which have preg & fat morphs so if the shapes you are interested in are ones I use, then I should be able to definitively answer for those.

Thanks Jenna!

I think it depends on whether or not the outfit is an original EA/Maxis item or not. I don't know for certain about those game outfits as I've never tried changing them but I would think that you would have to clone them first before making any changes to them. Otherwise, you risk changing game files which might corrupt your game. But that's just my guess.

For custom clothing though, yes, you can change the category on any of those without issues and without needing to clone them first. I've done that sort of thing frequently as I use custom elder meshes which match the meshes for adult/young adult. And x'58' does indeed change the clothing to be wearable by those three ages. The hex values for ages are as follows:
Age Value in Property Set
0x01 - Toddler
0x02 - Child
0x04 - Teen
0x08 - Adult
0x10 - Elder
0x20 - Baby
0x40 - Young Adult

Changing the age setting on clothing means that the clothing will be using the same mesh for all the ages you select. It will not, for example, make the clothing "fit" an elder mesh which is different from the Adult/YA mesh. The elder version will take on the same shape as the Adult/YA while wearing that outfit.

Nice, Julie!

I might just have to download these since I use TLBB as one of my regular bodyshapes. THANKS!

Thanks Julie! They look good.

It's just gone 8 o'clock and time for the penguin on top of your television set to explode.

I mean I don't have a clue what you mean.

Good to see you!

What sort of wrestling gear? "Real" onesies type of gear worn for school wrestling matches or something along the lines of GLOW wear or something else entirely?

Pictures would be most helpful.

Awesome!
