IMO...I don't really think it's the shorts/tee that is objectionable to some, but I'm visualizing a short, tight, multi coloured, way above the knees, pair of shorts and an also tight, short, multi coloured muscle shirt with exposed hairy chest and underarms dining next to our already too close MDR table. This convo has gone off the rails that we're looking down on the shorts/jeans/tee crowd. Clean and neat and appropriate for the fit on the body works for me. Other than that my haha moment would be the green tux so of that I'm guilty. 😉 For me, I'll continue with a nice cocktail dress or pants and beaded top and DH in casual slacks, dress shirt and jacket will look really good across the table...won't notice anything beyond our few square ft...unless...the hairy chest appears next to us...at that we'll move tables...not a problem.
