Anecdotal, but my wife is a stylist and is very much listening and providing individual feedback. She feels so bad when someone doesn't like what she picks so it's her goal to make them happy. Not all are bad.
I believe this. I love the idea of StitchFix but have not had great experiences with them. I finally had a stylist explain that they just don't get much inventory that matches my style preferences. This makes perfect sense, since they need to stock clothes that will fit/suit the widest variety of people, which leads to a lot of baggy, shapeless choices.
Don't forget drab colours and ridiculous lapels and pleats!
That much is true, she often gets frustrated that she can't pick from their entire inventory.
