Where'd you read that? Surprised that the king of Rick Thrift has handled any new post 2012 Rick. Also, you can clearly see that Moody Rick Jackets on Mr Porter and every other site uses YKK. SS15 Isn't out on sale yet. Maybe spread your bs on some other site you flake.
What do you mean by LNCC is including duties? Their pricing has always been inclusive of duties and taxes. If you get a bill from UPS or DHL just contact them and they'll take care of it. I've only been hit with a bill once and they told me to disregard and they took care of it.
You could def wear that with sneakers like Common Projects or something. I think it'd look good combined with other Gellar pieces like the sepia jeans, a t shirt and maybe white or black CP's. The zip doesn't exactly make it dressy and it looks pretty casual and cozy. Depending on how much you spent on it, i'd say keep, it's a nice piece.
