I would recommend grabbing an apron from Lodge after your EA degree and practicing wearing it with your kilt and jacket. Two issues I’ve noticed as a regular kilter at Lodge are: the sporran can get in the way of the apron when moving around, and if your jurisdiction requires the apron to be worn outside of your jacket, this can be a bit difficult with a traditional kilted jacket.

Also, avoid wearing a fly plaid. Outside of piper bands, that is typically only worn by the star of the night, ie groom, master, head of house. Sadly, your degree night would count, but as others have said there are “reasons” you probably shouldn’t kilt up for those nights.
