The occasion for this was the baptism of just born Infante Juan who became Count of Barcelona. Images of Infanta Isabel can be seen here.
The boy and men look awkward in their uniforms.
Everybody is dressed to the nines. All of the women wear mantillas, but the super-slender lines of 1913 cannot be seen here. Many of the details of the dresses are lost, but it appears that María Cristina and Infanta Isabel are wearing high necked dresses. I cannot resolve Infanta Luisa's neckline and the unidentified person in a darker dress is wearing a dress with a square or bateau neckline.
