Use a hand wash method for delicate fabrics. Soak in a vinegar water solution (it will clean well and remove grease, body oils, sweat, etc). Add some salt to the mix. Let it sit for an hour or so, rinse well. Your color should be set. Use a delicate wash from then on just in case.Does washing clothes in vinegar and cold water make them colour fast?
To make Easter Egg dye stay on the eggs, you dip in vinegar while the dye on the egg is hot.





So, soaking the garment in vinegar and hot water will make it colorfast...but the hot water could cause the garment to shrink.





Your best bet is vinegar with equal amount of cold water...allow it to soak. Then launder as usual. The vinegar smell will dissipate as it dries. And I assume that will be air dry.
In quilt making you use this method to set dies in fabrics, We have a huge problem in combining all the colors and fabrics and not having colors ';bleed'; onto each other. If your mum's suit is dryer safe I would toss it in the dryer too.
