In Britain, do you all have ice cream men, who drive around in trucks selling ice cream? And do they wear all white? Well, they don't wear all white here, but it's the cliché image. (they did once upon a time, you see).
I ask because I have a character dress in all white, who wants to say "I look like a Muggle ice cream man." But I wasn't sure if that was fitting to the area.
If the all white = ice cream man is not a 'thing' over there, please to be offering other suggestions. Milk man perhaps? LOL
