. . . Just head to Deseret Industries,
a magical thrift store located all over The West
(it's also a nonprofit, vocational rehabilitation facility, which means there's good karma all over.)
I've had really good luck here with various dresses/costumes.
(Here I am last December when I needed
a classic holiday gown.)
For Halloween this year I went to the D.I.
in downtown Los Angeles hoping to recreate this:
I found this dress for $6 that originally had a white belt sewn on. I unstitched the belt and gathered the hem for volume.
I added tulle and lace sleeves for an 80's touch and borrowed my sister's crinoline.
Don't worry, I had a Beetlejuice with me so people wouldn't mistake me for PJ Harvey or Amy Winehouse.
