Is your closet home to one or more Halloween costumes from years – and sizes – past? City Mouse Studio and Store in The Junction has your Halloween solution – proprietor Donna is participating in National Costume Swap Day on October 12th, as part of the “Green Halloween” movement: “As per their website, swapping half the costumes kids wear at Halloween would reduce landfill waste by 6,250 tons, equal to the weight of 2,500 midsize cars!”

Here’s how the costume swap will work: From now through October 11th, drop off gently used kids’ Halloween costumes at City Mouse (4218 SW Alaska) – which is open Tuesdays-Saturdays 10-6 and Sundays 10-5 – and get a token to use to pick up another costume there on Saturday, October 12th, starting at 10 am.

OCTOBER 10 UPDATE: Donna says you can also just bring your swappable costume on Saturday morning and swap on the spot, rather than making two trips.
