Based on a few different museum pieces I did a mock-up/prototype for a 16th-century pocket. These were worn under skirts, much like their 18th-century descendants. This is version 1, which I made a little roomier for our modern day needs. It will fit a phone, money and other often necessary items.
It is all machine sewn but the only stitching that shows is at the top where the pocket is sewn down to the silk taffeta waist tie.
I hope to offer a few of these in my Etsy shop soon.
