From going through google translate on Japanese sites. Most recommended that you wash and tumble dry from the start for Boncoura and Resolute. Seems like it’s a preference for a less contrasts fade jeans
On a side note there seems to be more preference amongst Thai LVC Facebook group for purely railing details along the side of the jeans and less crazy fade overall. To do this one has to use front loading washing machine and tumble dry regularly. Just make sure your jeans don’t shrunk too much.
For my upcoming pair pair of LVC 1955 I’m going to try to go through that route with hardly any crazy fade and just concentrating on the railing.
