don't forget - people think that victorians were all black, white and grey - they weren't. at this time, with the empire expanding into india and africa, bright colours were the rage with the nobility, and bright oranges, purples, and green, imported from across the empire were a great sign of status. a dress like that, probably the young daughter of a rich business man, would have been practically a very expensive gift wrap - the brighter and more attractive the better.
While i personally don't really care for the pink - would make you look like a marshmellow - theres no reason why it shouldn't be that color
