I actually did this one time with a pair of boots. I went to the dentist and upon sitting in the dental chair, looked down and I had on one black boot and one dark brown boot. They were almost identical in style, and the heels were the same height, so I didn’t notice until then. (Hey, they were on sale BOGO, so I purchased two pair!) So, I can’t say anything about her error. Sometimes, when you are rushing to get dressed, you make those mistakes. I’ve also accidentally worn mismatched earrings.
Different color? Okay. Just don’t go for two lefts or two rights.
Hey, I'm in a hurry, I cannot find two clean matching socks
because tomorrow is laundry day - and hey, these two are
quite similar shades of grey - and heck, my ride is waiting.
No one will notice, because I'm wearing long pants - I gotta go...
Sometimes life is tough. (LOL)
