1905 Baroness Olga de Meyer (in white with parasol) by Adolf de Meyer
From Wikipedia; sepia tone removed by gogm.
In this photo, Olga's hat is wide enough for the next decade while the rest of her frilly dress keeps with 1905 styles. At first glance, her bodice has a lace bertha, but she appears to be wearing lace epaulettes and rectangular lace lapels when the photo is enlarged.
