Went to the theatre last night - Fascinating Aida at the London Palladium - great show. This may be their last ever tour so catch a performance if you can. If you look them up, be aware that some of their material is NSFW. I'm also warning that some may not like the overtly political nature of some of their songs, but that's not a legitimate topic for this forum.
Saw plenty of heels, though mine were the only ones on a man. Examples seen on the tube (subway for left pondians) included black 4" block heel knee high boots on a young woman, 4.5", possibly 5", "nude" stiletto sandals on a woman out with her man. She looked at ease with them, even though most women would think of them as "taxi shoes". A few more thin heels up to 4" and loads of block heels up to 3".
Some recent photos of Michelle O'Neill, the new Northern Ireland First Minister, show her in possibly 4" stiletto court shoes. I wonder if she was wearing them when she met Rishi Sunak (UK prime minister and not very tall). Whatever you may think of O'Neill, Sunak and all again their politics isn't a subject for HHP.
