In the heat down south, whites don't stay white for long. Even with weekly blueing, bleach and lemon treatments, they still end up grey. My daughter's $80 white bra was that nasty grey. Everything I tried helped. It was a much lighter shade of grey but still not the brilliant white she loved.
Mom, the super seamstress to the rescue!
I found some fabric dye specifically made for poly fabrics. A very deep blue. I thought it would be beautiful. A pot of boiling water, the lid and the kitchen timer.
She now has a beautiful, indigo colored bra that she will get lots of wear out of and no embodiment when a strap peeks out. We are all happy that $80 didn't get thrown in the garbage.
