There are three ways (except for postwork)that I know of: using dynamic cloth, start with a scaled down figure and let him/her grow to normal size later in the animation. Or using no vertices between the start of the string/suspender and the end, which is very light on resources and works in all Poser versions, but is limited to strings/suspenders/straps that always should be straight. The third way is using morphs. Lots of morphs. A nightmare to pose well, and since the crosstalk bug has been eliminated in P5, a cloth creator should not rely on ERC. This is indeed a limitation of conforming clothing. Personally I prefer using dynamic cloth.

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
