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 one was created from a straw sun-visor repurposed into a lightweight, daywear, loose-crown bonnet. The crown of turquoise fabric is gathered along the brim and encircled with a 3” ruched ruffle accented with a narrow velvet ribbon. The pouffy crown is lined inside with white crepe fabric and edged in white eyelet to frame the wearer’s face. The ties are sheer yellow with silver sparkles, just for added flair!
The brim is 4” at its widest point in front. The crown measures 22” circumference but is soft and pliable for those with a slightly larger head size.
