Came across this glitch when getting married. I chose the black suit/tuxedo, and on my wedding day my character was wearing the wedding dress. I tried reloading from the quick save, as well as from my manual save, even tried passing out at 2:00AM with no difference in outcome, lol!
Sad I don't get to take any screenshots to remember this moment in the game, but at least I have some for the hilarity of it, lol!
