It’s so bad that my fiancée has some bras that say she’s a B cup and others that says she’s a D cup. In order to go bra shopping, you have to actually try them on to find out if they fit.
If I had to try on underwear to see if they fit, I might not bother with underwear at all!
It’s wild to me that people just buy the same shoe over and over. I’m not a fashionista by any stretch of the imagination; I just have one, maximum two, pair(s) of footwear per temperature slice, and I don’t even have any formal ones.
But even I would want something new, even if my old pair had served me well.
