[DAZ 3D](http://www.daz3d.com/) sells some great, detailed morphing trenchcoats (some of the preview images in the store are even *Matrix*-inspired). I haven't made use of the Michael version yet, but the image above was made with the Victoria version.

Other than that, your options are PhilC's trenchcoats (available here in the Marketplace), or the free Michael Duster at Ghastley Software.
