Actually, weddings were permitted in Lent and Advent preVII, at least in the US. They were for usually for two reasons: The couple was expecting their first child, or the young man (and in a few very rare cases, young woman) was in the military and being shipped out. The couple was supposed to keep the celebration simple due to the season. The church was not to be extensively decorated. They could have a Nuptial Mass, but sometimes no music. They were even told how to have the reception after the wedding (no heavy-duty drinking, nothing too extensive or expensive on the menu, sometimes no music or dancing). In these circumstances, brides did not often wear wedding dresses, but suits, and the young men their uniforms. There was often a wedding breakfast after being married at the early morning Mass on a weekday. So, there would be coffee, juice, eggs, maybe sweet rolls at a local restauant.
I know this from only reading about it in several books on WWII, the Great Depression and the like, but because my various older relatives were in both circumstances, and talked about it at family gatherings.
