How to straighten bikini strings on GF2?

Hello,
I hope someone can help me with my little problem.
How can I straighten bikini strings for instance on a GF2?
The strings always follow straight the surface shape of the character where they should span between two higher points of the shape.
This especially happen when the character has a voluminous or muscular shape.In result it looks very unrealistic.
I hope you guys can understand what I mean. :)
I would be very glad if someon has an answer.
Thanks in advance!

Do you have a picture that show the problem maybe ?
It's a bit difficult as the adjustments are automatic, if you have Poke Away! you can try to play around with that and see if adjusting the shoulders and upper arms may move the strings to a better place, not sure if that works though.
Sometimes the cloth have adjustments you can use to fix it also, depends on the cloth.
This is a common issue, not just with straps but with fabric generally - especially with morphs that aren't directly supported in the clothing. I would start by using a DForm, at least one per strap, and either position the field around the strap (for relatively simple adjustments) or moving the filed right away before using the Node Weight Map Brush to assign a weight map to the DForm for kinked straps. If that proves impractical it may be necessary to export to a modelling application and to create a custom morph.
Thank you all for your answers. Now that I know that it is a common issue I need to try out your recommendations to see what will work best, I guess.
Regarding the DForm I already tried to use it in another context and I experienced the issue where the DFormer affects other geometries that is too close to the one I actually want to morph. Maybe I did something wrong but don't know what. Anyways, thanks again for your help!
If you have the DForm affecting too much I recommend shoving the field right away and then using a weight map to control it - that allows very precise specification of which parts should be affected, though ti is of course fiddlier.
Thanks for this thread. I hadn't felt... up to experimenting with d-form, but it turned out to be _perfect_ for eliminating a very small but noticeable bit of clipping in the scalp of hair I was using.
Thank you Richard for your help.
now DForm works much better for me.
