From Me:

"Antibellum"? /facepalm First antebellum is Latin for "before the war" - ante means before and bellum means war. Therefore anything before 1861 is normally considered to be antebellum and it's normally used on items from the 1850's. Something from the 1860's would not be antebellum. Second, it's antebellum. Antibellum would better be used to describe the 1960's than the 1860's as anti is Latin for against. We use anti still everyday and it's pretty easy to figure out - antibiotics means against biotics or bacteria in this case. You probably hear antiestablishment a lot in the news - against the establishment, normally the government.

Since this dress was remade during the American Civil War - look at the waistline and the number of pleats on the back versus the front of the dress- it is neither antibellum or antebellum.  Although, it was originally made in the antebellum period.  

1857 Fashion Plate (antebellum)

Notice the double sleeve on the black and blue dress.  You see this on a number of pagoda sleeves in the 1850's.  

1864 Fashion Plate

The waistline and the pleats of the extant dress match more to the cream and white dress in the fashion plate above.
