To go along with your Bentley of a carriage, may I present the 1807 "Barouche Dress" from Le Beau Monde:

"– A Barouche Dress. – A complete shell of thin white muslin, worn over a white sarsnet slip, made quite short, open behind, and tied with small cords and tassels down the back; the muslin dress is made to the size of the throat, and the sarsnet slip with a high standing collar, trimmed round the edge with a French lace; long sleeves of white sarsnet, and short full muslin sleeves worn over the sarsnet. Long square mantelet of primrose silk, embroidered with a dark rich border of embossed ribband; the two ends are tied with a knot on the front of the bosom; a rich lace cap lined with the same colour as the mantelet, made with a point, and worn very deep on the left side of the face, and exposes the whole of the right. A small bunch of primroses is fixed on the center of the cap; long streamers of primrose satin ribband at the top of the crown. The front of the cap is trimmed with puffings of lace. Primrose gloves and shoes."

I only wish I had the fashion plate to go with it!
