Original: Gown with Day and Evening Bodices, c.1865

 I'm not entirely a fan of the purple crepe trim on the day bodice, but I love how it's applied to the evening low body. And the fact that these three pieces have managed to stay together for 155 years. (Five pieces if you count the undersleeves attached to the day bodice. They do appear to have matching trim at the wrists.)
