Spiders in my hair

What if clothes and accessories featuring animals and insects could function as magical talismans that summon real versions of the living things they depict? For example, a person wearing the Three Wolves One Moon T-shirt could actually produce three wolves (and maybe a moon) by making a simple wish.
What if I had a hairband with bejeweled and felt spiders on it and I accidentally trigger my accessory's magical power? I'd find spiders crawling all over my hair! Wouldn't that be terrible?!

Ok, I know I'm random and nuts.
