Sticking true to the time with crinolines everywhere. Floral's seem to be a major theme on the dressing in this film. Perhaps because of the positive imagery to the character of Cinderella. When she's out in amongst nature a songs being sung, she'll be capturing a sight of the prince, be taking flowers to her fathers grave in a moment of peace, her first kiss with the prince takes place when she's collected some flowers. This all shows in what she's clothed in, hats even the swing she's sat on.
Which then course creates a huge difference to her attire when she's a servant to her family, wearing more greys and dark blues, which show less of the dirt she's sitting in in order to clean.
