Facetime Ur friends before the function + get dressed together. Find the synergy between Ur wardrobes. Try stuff on in real time. No posing for pics β spin for the camera instead
one of my childhood friends did this so i dressed up as i did when i was 3 and her girlfriend dressed like she did on their first date and some people dressed as their freshman year going out fits etc etc... idk a good way to celebrate someone and also a good conversation starter if you have people from all over meshing at one function
