Blender's cloth simulation. It's been around for a while actually, even in 2.7.x, and has this neat sewing feature where any free edges without adjacent faces become stitches that pull the fabric together when you simulate. It's definitely poor man's marvelous designer in terms of features, but cool to mess around in for a while.

The newest blender 2.8.3 also adds a sculpt mode brush that also uses the cloth sim. It's kind of useful if you have a mostly finished clothing mesh that you want to add wrinkles too, but this way you don't even have to model the general form of the body. just subdivide some planes, sew em together with physics.
