Maxis default meshes? Which set?

[Ldyvamp]

I think am looking for some default meshes that will allow any maxis clothing recolors to be in warlokk sizes. So say I wanted a maxis recolored top in a rio size breast or a recolored maxis bottom in rio size. Also swimwear is a big issue for me. I love a lot of the regular maxis swimwear recolors that I have found in the community, but the breasts just seem to be too flat. Will these default meshes change that? What meshes would I need to download to get these results? I am so confused when it comes to the body shape meshes.
Also, would this be enabled for teen females too? I hope someone can help! Thanks and have a great thanksgiving!
