The dress is made from a self-striped cotton muslin.
Muslin was traded from Mosul. It was first imported into Europe from India in the 17th century and became a leading trade product of the East India Company. Indian muslins were much desired - they were handwoven and extremely fine.
British textile manufacturers started manufacturing cotton products including muslin but could not compete against the Indian products. Manufacturers petitioned the British government to implement protectionist policies such as bans and tariffs to restrict Indian imports. At the same time they invested, with funds from the profits made by the East India Company, in new manufacturing technologies which led to the Industrial Revolution. The Indian textile trade took a beating while Britain became the world's leading cotton manufacturer of the 19th century.
Printing on textiles advanced at this time, from manual hand blocked to machine rolled. This dress shows both methods.
It has been printed with three colours, using a mix of rolling and hand blocking. The pattern features floral bouquets in two shades of red and black. The difference in colour shade, shown on the flowers, was made by the depth of the engraving on the rollers so they were able to hold more or less ink. The green of the leaves has been hand blocked after the rolling. This is identifiable because it is not consistently in the same place.
The dress is completely hand-sewn as sewing machines did not become commercially available until the 1860s. It is secured by hook and eye at the back and has decorative pleats across the bust as well as piping around the edges.
The style of this dress is known as a walking dress but, interestingly, it also features an opening at the front to below breast level, indicating that a nursing mother wore it. We do not know the name of that mother, but it was a treasured item for her daughter Louisa Knight, born in Cornwall in 1846, and who married George Brewer Philp, a draper and clothier, in September 1878 in New Zealand. Louisa died in 1923 and is buried in Whanganui. In 1977 their granddaughter Aileen Greeves donated the dress to the museum, allowing us all to enjoy its qualities.
