Women during the Romantic period would wear perelines, which were wide, cape like collars that extended over the shoulders and down across the bosom. They were very popular and added decoration to outfits.
1830s undergarments: To keep the enormous sleeves of the dress from collapsing, large cotton pillows, called "plumpers" filled with eiderdown attached at the upper arms. Corded petticoats were worn to support the full skirt. Like the corset cording, the insertion of cotton ropes into casings around the petticoat made the material firm, yet flexible. Only after these undergarments were secured was the outer gown slipped over a woman's head and settled onto this ideal foundation.
