Found this thread now in the uk, soluble thread, will order as swimming is a hoby and I could modify swim suit, also have very flowing strappy dress to midify quite low at back so she does not wear with a bra, this would be the one for a night out spilage of water on back, also halter neck could have same effect, would have cam ready for that to.
Any other ideas though that would have a timed effect for zip stitching etc (im not good at sowing!) this way I can apply before we go out and then wait as the night goes on, there must be a chemical expert out there somewhere!
