Need guidance to make Virtual fitting room

Guy's please check the below videos to have a reference of what i'm planning to make.
It isn't the usual augmented reality stuff... I don't really understand how these guy's did it but i would love to learn from suggestions from top experts here...

My stats:
As far as i see the basic steps involved here are categorised to be the following three..
1. Creation of a body that resembles the user---This seemed a bit fine. We can use 3d body scans of kinect and import them to get the most accurate model of user.
2. Creating a 3d model of cloth---This sounded in two different ways..one is making a 3d model right at the start.. The designer should do that...We get that 3d model from the designer directly... The second way sucks a bit but works during inevitable cases i suppose. i.e., to obtain 2d pics of the cloth and create a 3d object using few softwares..{specify few software names if you know any}).
3.Rendering that cloth perfectly onto the 3d model created--- I had seen people doing this stuff on softwares like blender,optitex,marvelous designer etc. I want to know how this stuff works..

In the end i want to add...I'm making a website which have this Style me option. I need the above stated functions in the API(i'm not sure what they call it but heard it is API).

Struggling a bit to get this work done guy's. Let me know if some one can do it or atleast guide me through the steps involved, the softwares and languages used for this.
Read that they use wpf, c# for this kind of projects.

Here is a 2d pictorial version of the project. I will be glad if some one know about this too..
