I think it's a pretty big thing to ask a non-girlfriend/non-date to go out on a day shopping with you just to help you out.
Maybe it's a stereotype, but it seems based on fact that a lot more girls enjoy shopping for clothes than guys do and have a better eye for guys' clothes than guys themselves.
Lot's of services with stylists (who are mostly women) picking for clothes for guys & sending them to you in a pack are popping up, like The Cloakroom: https://thecloakroom.nl/en/
The only difference with this is that the guy and girl go out shopping in a city together.
But I also find it curious that the idea draws so many strong reactions - positive & negative. I think the name has an impact.
Interested to hear more thoughts from people.
