Hi, I'm old and rubbish with fashion. I'm going to birthday party in brighton at proud cabaret and the website says the dress code is 'Slaay with a capital S'. What the heck does that mean? 😂 I've tried googling and still don't get it. I was going to aim to wear a summer dress and trainers...would that count or would I need to take shoes to change into (I can't do heels) Help please!
