now almost very fashion brands have the shopping on line, but the problom is you can't try on
because the design different we can't totally trast the sizes so we might brought the wrong size one or right size but when you are wearing on you find it is not suit for you .
My ideas is
1) have you sizes ( arm，leg, BWH,……)
2)clothing sizes (regular size, arm，leg, neck, ……）
3）yourself body 3D image (like the modle)
4)clothing 3D image
then from the menu find which one you like to try on
the system will use your information find a right size for you
then you can view it by 360°,choose the colour , may be the size
your 3D body is not real but size is right but your face is real one
you can have a look this style is suit for your cast of features or not
this system can help you easy find a nice one for you
when you choose the system will tell you which part size is not right
