Slasque
Put on the ouvve! Sometimes there is also a theme for the slasque. Then you can add theme-appropriate clothing on top of the ouvve.
Jacket
Nicer everyday clothes. A blazer combined with something else, or just something that makes you feel good.
(We rarely have this dress code)
Dark suit
A dark suit or a nicer dress. A regular blue suit is also fine, or a skirt with a top as well.
Formal attire
Long dress or tailcoat, but a dark suit is also fine.
