So today the topic came up between a mixed group of male and females, 'What are you wearing?'
When I explained that the dress code was lounge suit, everyone looked blank. I was quite shocked as I kind of figured that 'lounge suit' was pretty straight forward and a common enough term. Apparently not.
After I provided my guide for lounge suit, everyone just replied 'well why can't they just say formal?'
We ended up googling the term (people trust google more than any other source, particularly if it a previously unknown term I have found in my experience) and after completing a criteria (time of day, temperature, occasion, for him/her), acceptable 'lounge suit' attire for him was a dark suit for winter with tie. Pretty straight forward. Lounge suit is essentially 3rd on the list of dress codes after very formal (white tie etc) and formal.
I'm just jealous that S gets to rug up in a suit for the wedding while I have to freeze it out in a dress.
