Freshbook t-shirt party, everybody gets given a white t shirt with the Facebook logo, you write your name on it so that people you meet can easily add you on Facebook.
UV paint party, just wear clothes you don't mind getting slightly wrecked haha
bright colours, glow sticks etc would be a plus. It's a shame we're not having a foam party this year because we had that at my freshers and it was awesome. Highly recommend going if the union puts one on later in the year.
However, the best event on the list there is Bierkeller for sure! Everyone raves about it, and after three years at Aber I still haven't managed to snag a ticket haha. Make sure you also join loads of clubs and societies and go on their nights out, they will show you all the many wonders of Aber's nightlife
