While the pretext may be the annual fashion show, many students use the event, held in a marquee on the university's Lower College Lawn, as an excuse to get into the party spirit.
The theme this year was The Bright Young Things, referencing the group of bohemian young aristocrats and socialites in the 1920s famous for inspiring bold writers and photographers of the period.
They were also well known for throwing lavish parties.
The theme was apt given that Saturday night's showcase included some avant-garde outfits, and the evening once again proved to be one very large, champagne-swilling party.
Now running for 22 years, this year's show was attended by 1500 guests.
Famously, it was Kate Middleton's appearance at the DONT WALK charity fashion show at the university in a see-through dress that helped focus Prince William's attentions when they were both students there.
In the past 20 years, more than £300,000 has been raised for a variety of worthwhile causes. The weekend's charity night was planned to raise money for the Association for International Cancer Research, which has its head office in St Andrews and funds research projects worldwide.
The show organisers hoped to build on the 2013 donation of £27,500.
But of course, the glitzy event aimed to showcase the pick of the fashion talent, with the work of up-and-coming designers revealed alongside established international brands.
