As the title says, what's been your biggest fashion No No.
Mine was a gorgeous little white dress I bought, can't remember what the occasion was for, but I saw this dress and thought it was perfect. Got the dress and shopped around for accessories to complete the entire outfit, shoes, bag, jewelry etc. The shoes were a fantastic pink and matched the bag perfectly, I was such a happy little bunny. Then off home all excited to show it all off to my husband.
Little problem is I am colourblind, very rare for a girl to be colourblind but even rarer to be tritanopic colourblind. I can not see the colour yellow, most oranges appear pink, blue and green can appear the same depending on shade.
Oh yes the gorgeous white dress I had bought was, my husband informed me during bouts of intense laughter, in fact a very very bright neon yellow, the hand bag was a lovely shade of pink but the shoes were a neon orange. To me it all looked lovely, but he assured me the colours simply didn't work. Needless to say the husband tends to check colours before I buy them now, unless it's a colour I am confident I can see
Mind it did throw us both into a phase of dressing up in the most garish neon clothes possible which gave a whole load of giggles
