Absolutely, services will be the way to go, the more personalised the better.
A retail shop is just a guess at the sort of things people might want to buy. How often have you found something you like but they didn't have it in your size or the colour you wanted. We have got used to having to visit lots of shops to find what we want. Sales have been used to to get rid of the stock that didn't find it's mark.
Online shopping is more likely to have the size/colour you want, but returns are a pain.
There is a role for a more service related offering, something like M&S's click and collect service. You say ahead of time what you want to try and then go in to try on, but anything you want and leave everything else to be returned painlessly.
Higher level service would be more like a personal shopping service, where you explain the sort of thing you want, such as occasion clothes, an interview suit or just a seasonal update to you let wardrobe. Again, you make an appointment to try on. Maybe combined with hairdressers and beauticians.
Another personalised service is the one Selfridges provided where your body is scanned and a pair of jeans made to suit your exact shape.
Maybe combined with a gym on premises.
Looking forward to trying some of these.
