Deep amber broach, or gold filigree buckle, confining the dress at the throat and waist,with bracelets en suite. Gold chain and opera glass. The woodland hat of fine plaited straw or chip, with ostrich feather falling on one side. A French cloak of bright purple sarsnet or velvet, lined with amber or rose colour, and trimmed entirely round with broad black lace and beading. Purple parasol, with deep white or amber awning. Shoes and gloves of buff kid.”
