I'm looking for a tight black dress for teen female that can look like the ones below. At least a mesh with shoes, they can be converse or they can be boots with heels for example, nothing too fancy. I can make a texture but i don't know how to mix meshes (for shoes). Thanks in advance!

Here you can find all clothes for female teens: http://sims2defaults.dreamwidth.org/55368.html
If you find the look you like, you just need to find it in bodyshop and use your texture on it.
That's how I create clothing.

I know that, i don't play the sims since yesterday, i used to make clothes before i learned how to download cc but all the teen meshes are too loose for what i'm looking fro but the adult ones aren't.

Well, as for meshes, I can't really say what would do, but from your pictures, you might find appropriate ones to use on older sites like lianasims2. Anyway, there are shoe swap tutorials out there:

The tutorial on garden of shadows lost the pictures due to photobucket, but the info should still be good.

Maybe some of these:

Unfortunately that style of CC tends to come with... questionable textures!

Thanks, i like the first ones by bershka, a little outdated shoes and textures more or less but i can try to add some other mesh for shoes and make different textures.

@Nysha the first link you left is beautiful formal dresses, here >http://www.modthesims.info/download.php?t=486317 but there is a problem I downloaded this myself,
I did downloaded the mesh that is needed that creator XmoonlightX said you need by creator Marz3na but when I look at these dresses in Body Shop and CAS.

All the dresses are hiding behind a long gown, ( All the same color gown ) in other word the actual picture of the dresses in Body Shop or CAS are "Not there" instead you have to click on each gown to find each dresses.
With things this way you do not know what style dresses you are looking for, so you have to guess, I like the dresses but don't like the way they are showing up ( so out they go ) it's a guess game.
