I know about dresscode, I know about Smart Casual. BUT we will be in the city all day and have our Afternoon Tea booked fairly late (6pm), directly after the National History Museum. We can’t be in dress shoes all day and will the girls could carry nice sandals to wear for tea, we can’t take my husband‘s size 14 shoes. How strict is the dresscode exactly? Does someone know?
