It’s interesting the people they chose. In the first photo there’s a black guy in a fairly standard casual/business outfit. But I think the thing they’re showing of is that they allow for natural hairstyles and facial hair.
Then then next photo is a white woman. But they’re showing her in pants (like men!) and that her shirt isn’t low-cut.
Next is a Sikh man and Muslim woman. Showing that they allow traditional head wear.
Finally is the photo I posted. Showing a woman in a skirt meaning they allow skirts but not too short and again a conservative top.
This brings me to the last example. What would you say they’re trying to say with the painted nails and earrings? I have my own suspicions.
It's supposed to be an evening white-tie tailcoat (what you wear when the girls are wearing full-skirted ball gowns, and a tuxedo just doesn't cut it anymore), but it's mixed with daywear and the waistcoat is all wrong and it ends up looking like a half assed version of regency attire. Unless you're a classical soloist or get to go to high society gigs you'll not see it except maybe at a wedding.
He should be wearing a swallowtail coat (which has a single button and sort of flares out in a curve to tails) if he wants ultra-formal daywear. It shits me.
