To fit it, you only need to slide Proportions and Muscularity to 100%, and Height and Weight to 60%.
I'm using the 1.1 Female Muscular Mesh proxy.

Here are the object and material files:

Now here is a chain mesh garment (still not chain mail) using Dupliverts. I've subdivided the shirt mesh, and parented it to a simple torus, which I rotate (in the Duplivert panel).
Note how close it looks to chain mail; this is probably good enough for a graphic novel, but not a close-up animation.

Okay, now I've got it. This is much easier. Using a cut-out piece of a wavefront export, create a duplicate version with a MultiRes level of one. Then parent it to a torus--I'm using a very small, simple one--and then make the duplicate objects real.
Finally join all the chain mail rings. The next problem is a much greater one--that of rigging it without distorted the rings--but let's enjoy how far we've come.

If your workstation is powerful enough, you can try the wavefront object yourself:

Now, there is a way to animate this, but it is pretty terrifying. It's all about committing to a 'geek lost weekend'.

Each frame can have its own Duplivert, and then exported as Vertex Keyframe Animation. Ouch!

Be that as it may, here is a short animation:
