This is a fun thread. On one of our first shopping trips as a married couple my young wife and I were exchanging sizes for gifts when I asked her "what is your lingerie (pronounced just as it is spelled linger - e) size". She said she usually wore about 6 in lingerie (correct pronounciation). So I asked her if the French size would be the same as American? I really thought there was French lawnjurai' and good old American women's underwear called lingerie. She still teases me about it. Any other guys fall into this trap?
