Step 1: Materials
We were lucky to find a child's vest, pants, shirt and matching bow tie for $3.99 at a thrift store. I think it was intended to be a fancy Christmas outfit, but it's perfect for a Gold Rush era costume.
At the thrift store, we also found a bag of miscellaneous sewing stuff that contained some black elastic trim.
To turn the elastic trim into arm garters, you'll need scissors, a needle and thread.
While this was a costume for a baby, you can make an adult version just as easily with adult sized clothes.
Step 2: Making Arm Garters
I measured my son's arm and cut two pieces of the elastic trim to length (adding a bit so that he can wear them again when he's a bit bigger).
I sewed together the ends to finish the garters.
Step 3: Final Touches
I drew a nice Klondike mustache on my son's face with a brown eyeliner pencil. (Since he's a drooling teething mess these days, the mustache lasted less than 15 minutes, but it was cute while it lasted!)
Accessorize with some antique-looking barware and you're ready to serve the Gold Rush crowds.
