I’ve yet to see anyone with one of those Uniqlo bags that have gone viral.
Longchamp Le Pliage bags are very popular and I have seen numerous people with them.
I have not seen many of anyone decked out in obvious designer gear. I’ve seen plenty of people with designer bags.
People dress how they want and I have not seen any noticeable trends other than to say people are dressing for comfort ( trainers).
