1890-1919. White tie tuxedo illustrations. Note the unusual styles in the 2nd and 9th image (the cuffs in the former, and the lapels and waistcoat in the latter). These are earlier forms that are no longer considered acceptable.
Conversely, the black ties and waistcoats in the 3rd, 4th, and 5th images were dinner jackets that later evolved into the modern black tie tuxedo. These were originally not acceptable in mixed company.
This is me tonight. Got about 4 hours of sleep last night, dropped Dad off at a hospital to have his knee replaced, had a final and then spent about 8 hours in the hospital waiting room. Five of which were spent waiting for my Dad to be put into a room. I wanna curl up and sleep forever.
