Simple, loose crown bonnets of varying styles were common during the Regency. The array of fabrics, colors, and decor were truly endless. Visit my Pinterest for numerous boards containing fashion plates and extant examples from the period to see what I mean: www.pinterest.com/sharonlathan62
This bonnet has a narrow, 3” brim constructed of heavy stabilizer enforced with millinery-wire and then covered with cotton mull and fabric. The main fabric is lightweight cotton of teal with a beautiful paisley print. The puffy crown is unsupported, gathered at the base and edged with a three-tier ruffle of white crepe, the paisley print, and pale teal lace. The neck is decorated with hand-created ribbon flowers and lace. The crown interior is fully lined with the white crepe and edged with the pale teal lace.
Aside from the decor (which was attached with heavy-duty hot glue) the entire bonnet is machine and hand sewn.
Brim depth is 3”. Brim front to center back measures 10”. The crown opening measures 22” circumference with some give for a larger head size.
