I think it’s Cunard not even trying to enforce the dress code. The other evening on QM2, when it was Red & Gold gala night, one younger gentleman went to the theater in a t-shirt and gym pants, while many many older gentlemen had shorts and Hawaiian style vacation shirts on. Apparently not a problem for Cunard at all, they just walked in and took some nice seats. And this was at 8:00pm in the Royal Court Theatre on a gala evening!
