We have no information on who wore this dress or when, though it has features characteristic of the later 1860s. It uses a startling emerald colour silk taffeta, distinguished by a shamrock pattern, so perhaps it had a proud Irish owner. The dress is trimmed with a black velvet band: at the hem, on the lower flounce, above and below the smaller upper flounce, on the sleeves at the cuff and as an epaulette effect, and with the square yoke on the bodice leading down to a point at the back. The velvet is accentuated with a strip of brown lace on the cuffs and bodice. The dress has decorative velvet covered buttons and fastens at the centre front with hook and eyes.A strip of black tulle sets off the neckline. The bodice is high waisted and comes to a peak at the front centre with stiff boning here but not in the back. The skirt is flatter at the front with extensive pleating at the centre back, covered by a gathered peplum decorated with a bow. There is a hidden pocket in the front seam of skirt. The sleeves are very distinctive. They are full length and narrow at the wrist with the velvet trim repeated on the decorative pleating at the cuff. This dress would have had a crinoline support but it is slightly longer at the back suggesting the flatter fronted crinoline of the later 1860s. A small bustle pad has been added later suggesting that it was reused after crinolines had passed out of fashion.
