Dickie,
Please feel free to wear your gown; I'm not how sure how many others will be though.
If you're in Dundee 4ish you will be on time for the first round. However on Saturday, if one is not outside the Union at 9:30, one can't get in until 5 pm (crazy as it sounds, it's true).
The Semis should start just a bit past 4 and I am looking to start the final at about 7 in LPH.
Hope this answers all your questions.
