Yeah, this one is sticky.
A couple of us have spoken privately about the best advice we can give you, but I just don't know enough about it to drop in my two cents worth.
I think Singapore is pretty close, this type of thing could get messy and cause you some issues.
I'm sure someone here would have a better idea, you just have to wait til they turn up with their pearls of wisdom unfortunately : )
My own take on it, if the replica carries a licensed name, then absolutely no way, that's clear cut.
If the item is a brand inspired replica, meaning that it looks like, but doesn't carry any of the licensed branding....well, that's where it's gets a little too gray for me to be sure, so...no comment lol
