Uncertain what the color transfer is from.

It looks as though dark denim jeans transferred color onto the white shirt.

The shirt is brand new and has not been washed so uncertain how easily the markings can be removed.

If you are good at removing stains this shirt find may be for you….

Pictures above may not show all of the markings but show the obvious ones I was able to see:

On right sleeve, on chest and stomach, on back
