Black Knickers

I'm almost to consolidate a load of underwear into the machine - then I wash with black panties white bra?

Yes they are beautiful

If you like gray arms, go ahead. As usual, of course, is to Separate the whites from the shadows, so delicate (clothing) from cotton, etc.

Never wash the "dark" with "white" always wash separately because the shadows will a gray and white on white does dirty they are.

Yes, but eventually you get bras gray I'll wait until I have towels or other whites to wash or you'll go out and buy new bras white.

I do not want. I prefer to wash a single item that ruin things that I paid for.
