I live in a densely populated area in between NYC and Philly. I would say that I observe a mix of contemporary and luxury brands. I’m in my 30’s but I see people in their 20’s with luxury designer bags but teens don’t seem to carry any bags. I mostly see them with their phone and maybe keys attached to a little wallet/card holder. Most popular brands overall are MK, Coach, Marc Jacobs, Tory Burch,, LV, Gucci - occasional Prada and Chanel. I don’t see many YSL bags but I’m a huge fan of YSL so I like not having the same bag as everyone else. There is a certain area and mall that has all luxury shops and it was mentioned in here before - Short Hills Mall. There is pretty much nothing but high end designer bags there haha! Hermes and Chanel are adored in the wild haha!
