Then ya wanna Clothify yr dress...simple enuf. When ya get to Current Collision Object, simply select every element that the cloth will touch. This means that if yr plannin' a "hand on hip" pose, ya gotta select the respective hand/ finger elements regardless of whether the cloth Drapes over them. Before leavin' I like to adjust Collision Offset as well...this determines the distance from the cloth to the figure. A cotton dress obviously won't hover 1" off yr figure's shoulders, so I usually drop this to .25; a small enuf measure that it'll look natural. I won't get deeply into the differnt Cloth Groups, but in this instance I put the buttons in the Rigid Decorated Group, 'cuz they're...uhhhhh...rigid decorations. On this dress that was simple, as the buttons have their own material assigned, so I hit Edit Rigid Decorated, then Add Material> buttons.
