Fiesta fashion.

The traditional flamenco dresses were out and about on Saturday.  Girls of all ages and their mothers  wearing their brightly coloured outfits.

From Wikipedia:
The outfit was originally worn by Spanish Gypsies (Roma people), but is now generally thought of as typically Andalusian and is particularly associated with Andalusian festivals such as the Seville Fair (Feria de Abril). The outfit originated in the late 19th and early 20th centuries when women vendors dressed in modest calico gowns adorned with ruffles came to the fairs along with livestock traders. In time, women of the propertied classes copied these outfits worn originally by rural workers. Ever since the Seville Fair of 1929, the traje de flamenca has had a status as the official outfit of the event.
