Whidbey Harvest Moon Market

Can anyone tell me what the vibe of this event is like? I know it's only the second one, but hoping to gain some insight. I've read everything I can find, and see the features and activities they'll have, but is this a "dress up like it's spooky ren faire" event, or a more mainstream "dress up like whatever" event? I see it's a fundraiser for the Whidbey Island ren faire, but I just want to get a full picture of what I might encounter before I commit to going. Thanks!
