You can literally wear whatever you want, there aren't any rules. Some people dress up, but most don't. Smart casual would be perfect.Sooooo if one were to be attending a musical in the coming months and had no idea what would be appropriate to wear.... What would the fezzas advise? Obvs won't be pulling out my spandex sequinned crop top and clacky mules (this time). Smart casual is fine though right?
