I'll admit it, I've been the Little Mermaid twice for Halloween, once when I was 5 and later in my 20s — so you can bet my costumes looked totally different. When I was little, I cried as my mom forced ballet slippers onto my feet, insisting that mermaids have fins. Last year I nixed the wig, sported a bandeau bra, and went for sky-high heels.
In other words, as we get older, we get more, well, daring with our costumes. A quote from Mean Girls sums it up perfectly: "In girl world, Halloween is the one night a year when a girl can dress like a total slut and no other girls can say anything about it" — even if that doesn't sound so rational.
But at what age do we start shedding the layers and slipping on the thigh-highs — and which Halloween costumes get the raciest as we grow up? Scroll through to take a look at the way some of the most beloved childhood costumes evolve, and maybe think twice about ditching some of your outfit details this year. What's a pirate without a poet blouse, anyway?
