Woman wearing oversized man's dress shirt -- unbuttoned

[Innoventive Software, LLC]

Unfortunately, unless you have money to pay for this special model, it can't literally be done. There are some work arounds, however... the easiest being to apply a texture to the existing woman's short sleeve shirt (which is open collar) to create the illusion of it being opened.

I've created a simple version below, which you should save by RIGHT+CLICKING or CONTROL+CLICK (on the Mac) and then saving to your textures folder.

Hope this helps.
