Single-breasted jacket worn by Captain Alexander Nairne (active 1815–1832) of the Honourable East India Company. The jacket is of indigo-dyed peau-de-soie, with black collar and cuffs of the same fabric. The stand-up collar features two embroidered twists of silver thread on each side and, in keeping with the style of the late 1820s/early 1830s, these have become very large and flat. The sleeves are loosely gathered at the shoulder and terminate in a round cuff also embroidered with two silver twists. In the centre of each twist is a small gilt brass button of the Honourable East India Company pattern. Each cuff fastens with a small black self-covered button.

The bodice and collar are lined with cream silk twill and are quilted in vitruvian scroll, interlace and wave patterns. The breast is padded to create a fashionable rounded effect. The tailoring to the back shows the typical ‘diamond shape’ popular throughout the 18th and early 19th centuries.
