The Body Acceptance Committee (the folks behind the annual Body Acceptance Week) are hosting "ReSize!"
Bring an old item of clothing that doesn't fit, and they'll give you the supplies and expertise to make it into something new and fashionable!
From the Facebook event:
Stop trying to change your body to fit into that special outfit. Accept your body for what it is and bring in that pair of jeans or shirt to repurpose it into something that you can use or wear. All supplies are provided to personalize your garment of choice.
