A mother has sparked outrage online after asking for advice on whether she should wear white to her sister-in-law's wedding.
The British woman, known only by her username 'Badbird', took to Mumsnet to share a picture of a monochrome outfit she was thinking of buying, before questioning fellow mothers whether it was inappropriate.
Her snap, taken from clothing site Twenty-Six Fashion, showed a white semi-sheer lace midi skirt priced at $76 and a short-sleeved black polo neck sweater.
But users quickly flooded the thread, warning her against committing the cardinal sin of wearing white to a wedding, the DailyMail reports.
