Which one is it? I’d recommend either either anika_personalshopping or conniecollective - they are both proper. Anika works for Selfridges and Connie did and has now gone it alone. They have access to either stock in the stores that they can get their hands on first, or they also work directly with the brands at being able to get a lot of the rarer sold out pieces. For Hermes I’d go to these two
A lot of the other “personal shoppers” now are also legit, but they won’t have an association with any shop or brand and they’re more just people buying to re-sell at a profit - which is fine if you’re just desperate for something sold out or in a rush. For example my ex-friend runs @Crepzstation, they don’t have any real affiliation with the brands but they make it their mission to get sold out stuff or source it, then charge people over the odds. But as they work with a load of footballers it gets them a good rep, as they’ll probably be doing it for less profit for them. It also gives people the luxury of going “I want these new Dior shoes in a 9 in this colour” and then it becomes my friends mission to look for them, buy them and re-sell to them at this premium and the footballers don’t have to lift a finger. They do also sell things under RRP when they can get hold of bulk amounts from brands.
On the FLIP side, some of the more un legit personal shoppers can be fake
