esha has some really nice looking dynamic clothes for M4 here in the marketplace.  converting clothes from conforming can be very rewarding, but it's kind of hit or miss whether the mesh will work well as a dynamic piece.  i'm personally working on about 3 outfits for  M4.  unfortunately, my texturing skills (or lack thereof) are holding me back, so i don't know when i'll finish.  i'm good with materials, and i'm even decent with any kind of texture that involves obvious patterns and decorations and such.  but the subtle detail of plain fabric eludes me at the moment.
