Clearly, you can order Halloween costumes from the Internet, but since the Bay Area is full of folks who think outside the box, we’re providing a list of resources for where to buy costumes locally as well as where to find materials for making your own.
[Where to trade costumes | [Where to buy costumes | Where to make costumes]

When my son was younger, this was the time of year to which he and I most looked forward. He would have a costume in mind and I would get to figure out which components we were going to make and which ones we needed to buy.
Once, I made this clown costume from scratch, having bought the fabric at Stonemountain & Daughter, but purchased the clown wig and Snazaroo face paint at the Halloween Spirit Store (locations below).
Another year, we bought the whole Santa outfit, but I assembled a crafty undershirt strategy that contained a jolly-sized belly. (Hard to see in this photo, so you’ll have to believe me.)
Here’s where to get costumes and materials to make them yourself in the East Bay

“Local Buy Nothing groups are also a convenient option for finding or giving away kids’ costumes”, adds Berkeley mom of two, Maureen.
Second-hand clothing stores
In October, Goodwill, Salvation Army, and other thrift stores often sell used kids’ costumes, but they also have the makings for tons of homemade costumes. An old prom dress can become a princess or fairy, for example. If you have low-level sewing skills, it’s easier to start with a manufactured garment and leverage the existing hems or zipper closures.

Kids’ used clothing stores start putting their costumes out during the first week of October. Check out the following used clothing stores for baby, toddler, and preschooler sizes.
- Kelly’s Corner (Oakland)
- Mommy’s Trading Post (Alameda)
- Once Upon A Child (Newark)
- Moments Shared (Vallejo)
“Poshmark is great for kids costumes”, adds Oakland mom of two, Bekah.

Knowledgeable staff who can help you strategize your craft project.
