Vintage Butterick shark sewing pattern

This year is the first year I’m planning on sewing a Halloween costume for my little guy. He’s currently obsessed with sea life in particular whales and sharks. For some reason there are not a lot of either sewing patterns in toddler sizes that I could find other than this vintage Butterick. I found this one on Oh Patterns over on Etsy : https://www.etsy.com/shop/OhPatterns . Which I’m only now just realizing they are located in Alamo California which is about 30 minutes away from me.

I’m looking forward to trying this pattern out and hopefully my little guy will actually want to wear it!
