Just a random poll-
maybe the Louis Vuitton Monogram Cerises Speedy 25. it's been discontinued for ages but everyone's still dying to get their hands on one, and they can only get it used now.
There's always the Hermès Birkin and Kelly!
I agree it seems like everyone is loving on those bags.
louis vuitton cerises speedy 25 and certain balenciaga especially the one from older years like 2001-2004
