3D Custom Shoujo (abbreviated TDCG) is an eroge that features cell-shaded grapics, enabling you to make moe-esque characters. It is nowhere as detailed as Jinkou Shoujo 3, but it has its own quirk. This game is fully on Japanese, so you need a PC with enabled Japanese locale to be able to play it correctly.
Since posting pr0n is against Wikidot Terms of Use, I will not answer any questions related on how you can get the game. Well, not here anyway ;)
The menu is quite easy to navigate, you can mix and match clothing item, though nowhere as customizable and variable as Jinkou Shoujo 3. Interesting point that you can pick front hair (bangs) and back hair, in addition to "idiot hair". The colors are also limited, and strangely enough, there are no red-colored hairstyles.
Finally, you can have a 3D-editor mode at Maya class, in which you can alter the bone position of the girls and let them pose as you like!
