Why do young ladies think it is acceptable to go to the shops in their dressing gowns?

It is not. If you are cold, get dressed properly and put on an appropriate coat. Often I see a certain type, who will go to their local shop in the morning, who'll actually apply makeup but neglect the effort to actually get dressed properly.

Obviously they are parading themselves to the men who work in the shop and hope that showing up in such attire in someway entices them. If they are correct about that, these men are not worth bothering with. Standards exist for a reason.
