The most popular costume I saw out today? Person Dressed For Winter. I'm used to Halloweens spent covering costumes with winter coats; Chicagoans not as much (though it depends on who you talk to). I definitely went as "Bundled Up" today. I didn't trick-or-treat, but I got to hand out candy at work. That's my favorite part, really--loading other people's kids with sugar, scoping out the creative/scary costumes, staying warm inside.
I saw large women in tiny hats, little girls in giant hats, superheroes, wild creatures, cops, robbers, & dinosaurs. I wasn't stingy with the candy. The best part? I didn't spend any money on the candy and I get to raid the leftovers tomorrow.
