Enzoani Dartmouth Long sleeve unclassified dresses

Size 10 Dartmouth Blue by Enzoani dress (silk taffeta). Never worn or altered. I bought it for my wedding but have fallen in love with a different gown. Include bolero jacket and detachable flower for the hip. It's a small fitter, I'm a size 2-4 normally and I'd probably have to take this in to a 6-8.
